Chronic pain: Why does alcohol worsen it?

Chronic Pain and Alcohol Abuse

Over time, drinking can also damage your frontal lobe, the part of the brain responsible for executive functions, like abstract reasoning, decision making, social behavior, and performance. Past guidance around alcohol use generally suggests a daily drink poses little risk of negative health effects — and might even offer a few health benefits. People who binge drink or drink heavily may notice more health effects sooner, but alcohol also poses some risks for people who drink in moderation.

Drinking to Ease Chronic Pain Ultimately Makes It Worse

Each of those consequences can cause turmoil that can negatively affect your long-term emotional health. And prolonged alcohol use can lead to mental health conditions like anxiety and depression. Pancreatitis can be a short-term (acute) condition that clears up in a few days.

Alcohol Use Disorder and Chronic Pain: An Overlooked Epidemic

Over half of people with alcohol use disorder experience significant, persistent pain. This phenomenon is more common in women, affecting around 60% of cases, than in men, in whom it affects around 50% of cases. Psychotherapy be extremely beneficial in dealing with chronic pain’s mental and emotional aspects. Because physical and emotional pain are related and activate one another, addressing depression, sadness, frustration, irritability, anger, anxiety, and fear has multi-level benefits. By shifting perspective and adjusting one’s thinking, it’s possible to change emotional responses and, in turn, dramatically decrease the level of suffering. It’s not unusual for people with chronic pain to consume alcohol to self-medicate—to drink to help sand down the sharp edges of their pain and turn down the volume of their discomfort.

2. Pain, chronic excessive drinking and alcohol dependence

Chronic Pain and Alcohol Abuse

Another family history study on prepubertal children suggested that the risk of prepubertal onset of major depressive disorder in families with a high aggregation of affective disorders is higher when there also is a high prevalence of AUD in the families (Puig-Antich et al., 1989). Thiamine, folate, niacin, vitamins B6 and B12, and vitamin E are all needed for proper nerve function. Drinking too much can alter levels of these nutrients and affect the spread of alcoholic neuropathy. Fortunately, abstaining from alcohol can help restore your nutritional health. Genetic, psychological, social and environmental factors can impact how drinking alcohol affects your body and behavior. Theories suggest that for certain people drinking has a different and stronger impact that can lead to alcohol use disorder.

Neural Bases of Pain

Chronic Pain and Alcohol Abuse

Increased IBA-1 and CSF-1 expression was observed in spinal cord tissue of both hypersensitivity-abstinence related and neuropathy-alcohol mice, and increased IL-6 expression and ERK44/42 activation in mice with hypersensitivity-related to abstinence, but not in mice with alcohol-evoked neuropathic pain. Despite consistent evidence from the animal literature, and well-documented historical use of alcohol as an anesthetic (e.g., Shealy & Cady, 2002), only a few experimental studies have been conducted among humans to test the causal effects of acute alcohol administration on laboratory pain reactivity. Human laboratory pain models allow researchers to mimic signs and symptoms of painful medical conditions without causing lasting damage. Common paradigms include mechanical pressure, electrical stimulation, and exposure to thermal stimuli. Excessive alcohol consumption is also a known causal agent in the development of alcohol-related neuropathy, which can be characterized by damage to sensory, motor, and autonomic nerves, potentially due to direct neurotoxic effects of alcohol on the central and peripheral nervous systems (e.g., Chopra & Tiwari, 2012). Pain is a predominant and early feature of alcohol-related neuropathy, and treatment typically requires both acute and long-term pain management (Chopra & Tiwari, 2012; Njamnshi & Wisysonge, 2010).

Chronic Pain and Alcohol Abuse

Pain is a multidimensional and subjective experience that in its acute form is essential for survival, but in chronic form, pain is a disorder that negatively impacts quality of life. Neural substrates involved drugs brains and behavior in initiating and maintaining chronic pain include dysfunction in descending pain pathways and reward network circuitry. AUD involves preoccupation or craving, intoxication, withdrawal, and negative affect.

  1. For example, longitudinal studies may test whether persons with chronic pain are at greater risk for the development or persistence of AUD.
  2. Evidence derived from both animal and human studies indicates that acute alcohol administration may confer short-term pain-inhibitory effects.
  3. Third, given evidence from animal studies that acute pain-inhibitory effects may subside with chronic alcohol exposure, human trials are also warranted to determine whether tolerance to alcohol reduces acute pain-inhibitory effects.
  4. This may be the main enabling factor in developing chronic pain through reinforcement in susceptible individuals, and a behavioral model of chronic pain (the operant model; (Fordyce, 1976; Sharp, 2001)), suggests that positive and negative reinforcement of acute pain behaviors may lead to the development of chronic pain.

Two different molecular mechanisms may be the reason chronic alcohol consumption results in an increased sensitivity to pain, according to research published in the British Journal of Pharmacology. Research designs that allow for naturalistic assessment of covariation between pain and alcohol consumption would yield important information regarding event-level temporal associations. For example, ecological momentary assessment (EMA) may provide an optimal method for assessing such covariation in near-real-time.

Chronic Pain and Alcohol Abuse

Therefore, it is possible that some individuals may hold expectancies for pain relief via alcohol consumption. Also, given initial evidence that persons who are alcohol dependent experience increased pain during periods of abstinence (Jochum et al., 2010), it seems reasonable to hypothesize that increased pain may precipitate relapse to drinking. Impaired cognition can modulate the cognitive-evaluative dimension of pain experiences, both as a reinforcing factor for alcohol-seeking behavior (as alcohol is known to alleviate pain) and also in how pain is perceived. Additionally, physiological cues accompanying alcohol consumption can influence drinkers through modulating their expectancy. This may be the main enabling factor in developing chronic pain through reinforcement in susceptible individuals, and a behavioral model of chronic pain (the operant model; (Fordyce, 1976; Sharp, 2001)), suggests that positive and negative reinforcement of acute pain behaviors may lead to the development of chronic pain.

It can take longer to recover muscle strength and movement in chronic alcoholic myopathy, but it can be reversed. About 85% of people recover within 2 to 12 months of quitting all alcohol and are fully recovered within 5 years of sobriety. The three depressive diagnoses were combined into one factor (Depression) to represent the participants with a history of any depressive disorder (MDE, MDD, or PDD). Chronic Pain refers to the participants with a history of both pain diagnoses (chronic back/neck and frequent/severe headaches).

Results of this study may play a pivotal role in explaining the incidence of depressive disorders in individuals suffering from chronic pain disorders and who have an ALC history. Routine screening for current or past drinking history [46] by primary care physicians is recommended. Such screening can assist in understanding the relationships between ALC and depression as comorbidities in association with chronic pain disorders, thereby tailoring treatment strategies to enhance positive outcomes [47]. By stipulating that the allostatic state arising through actions by alcohol, trauma (stress) or injury does not depend on the temporal sequence of exposure (i.e., the insults are functionally substitutable) our model is compatible with many hypotheses. Nevertheless, laboratory studies suggest that the presence of hyperkatifeia and enhanced responsiveness to painful stimulation may not always be sufficient to increase alcohol drinking.

It is also possible that participants who were considered problem drinkers may have developed a tolerance to alcohol (e.g., Schuckit et al., 2008), which could explain why a higher dose of alcohol was necessary to achieve analgesic effects in that group. The sample size for our cohort with severe/frequent headaches was smaller than our other cohorts. This may account for the lack of statistical significance for the difference between the ALC and CTRL groups in age of onset of depressive disorders. To confirm alcohol and drug detox treatment blog this, we conducted additional analyses in which we included individuals who had a history of arthritis/rheumatism (one of our exclusionary criteria). By doing so, we increased the numbers of subjects in all three cohorts of no pain, chronic back/neck problems, and frequent/severe headaches. Accordingly, we found that the ages of onset of MDE, MDD and even PDD were consistently younger in the ALC cohort independently of the presence or absence of the chronic pain disorders compared to the control cohort.

These findings could help explain why some people with chronic pain drink excessively. “There is an urgent need to better understand the two-way street between chronic pain and alcohol dependence,” says senior author Marisa Roberto, PhD, the Schimmel Family Chair of Molecular Medicine, and a professor of neuroscience at Scripps Research. There is also reason to believe that expectancies for pain relief via drinking may have a potent influence on pain reporting (Pollo et al., 2001). Individuals may come to hold beliefs that alcohol will help them manage pain a dmt trip ‘feels like dying’ and scientists now agree bbc three if they have previously perceived a reduction in their pain (or pain-related distress) when drinking. Given evidence that alcohol expectancies may be influenced by socially shared and transmitted beliefs (Donovan, Molina, & Kelly, 2009), it is possible that expectancies for alcohol-induced analgesia may be shaped by social depictions of alcohol as a stress-coping agent. However, we are not aware of any studies that have attempted to assess whether participants held expectancies that drinking may mitigate pain in the context of laboratory pain induction.

It is likely that the more prominent neuroplastic changes in these cortical regions due to direct or indirect effects of ALC may contribute to a stronger corticostriatal dysregulation and hence the higher likelihood of depression that we observed in association with ALC. The goal of the current review was to integrate evidence derived from relevant psychological, social, and biological empirical literatures to generate testable hypotheses that may inform future research and the development of novel interventions. The current review extends previous work by examining associations between pain and various levels of alcohol consumption (including low-to-moderate levels of drinking), and by identifying psychosocial mechanisms that may underlie these relations. We begin by providing an overview of the background and terminology relevant to the study of both pain and alcohol, reviewing data regarding the co-occurrence of pain and alcohol use disorder, and discussing potential confounds and relevant third variables. We then review studies examining both the effects of alcohol on pain and the effects of pain on alcohol use, and integrate these findings to conceptualize a series of reciprocal interrelations between pain and alcohol.

Consideration of conjoint treatment of AUD and pain is essential, especially given the bidirectional relationship between the two, including the dampening effect of alcohol on pain perception, which may lead to drinking as a coping mechanism, and thus, poor AUD treatment outcomes. This point may be particularly relevant for individuals exhibiting pain within the context of a more severe health problem, such as HIV or sickle cell disease (Levenson et al., 2007; Merlin et al., 2015; Merlin et al., 2014). As noted in previous sections, alcohol has been shown to have acute analgesic effects (e.g., Perrino et al., 2008).

Chronic pain syndromes have the propensity to trigger the risk of initiating alcohol abuse, or triggering relapse in individuals who had attained abstinence. Characterization of the interrelatedness of alcoholism and pain allows for early detection and treatment of patients at risk for developing chronic pain conditions, and for preemptive interventional approaches to reduce the risk of consequent alcohol abuse. Conversely, there is some prospective evidence that older adults who endorse more severe pain or a greater number of painful conditions may ultimately go on to reduce their alcohol consumption (Bobo, Greek, Klepinger, & Herting, 2012; Brennan et al., 2011; Brennan & Soohoo, 2013). However, each of these studies sampled older adults who did not necessarily have chronic pain, reported low levels of baseline drinking, and whose patterns of alcohol use may not generalize to other age groups. For example, an age-related decline in alcohol use tends to begin following young adulthood (Shaw et al., 2011), and older adults have evinced a general motivation to reduce alcohol use in response to health concerns (Dawson, Goldstein, & Grant, 2013).

The ventral striatum receives its primary input from those same cortical regions [40,41]. It is possible that differences between comorbid depression with ALC, and comorbid depression with chronic pain, may arise from differences in connectivity of cortical regions and the ventral striatum. Indeed, a recent meta-analysis by Ng and colleagues [42] has challenged the common notion that MDD is primarily linked to deficits within the reward circuitry, particularly the ventral striatum. Instead, they proposed that dysregulated corticostriatal connectivity may underlie reward-processing abnormalities in MDD.
