Alcoholics' Pain Sensitivity: Science Or Myth?

Alcohol has been used to relieve pain since ancient times, and laboratory studies confirm that it does indeed reduce pain in humans and animals. However, the relationship between alcohol consumption and pain sensitivity is complex. While moderate alcohol consumption has been linked to reduced pain sensitivity, particularly in men, chronic alcohol abuse can lead to increased pain sensitivity during withdrawal. This is due to changes in how the brain processes pain signals and immune system activation. Additionally, tolerance develops to alcohol's analgesic effects, leading to a vicious cycle of increased consumption to achieve the same pain-relieving effects. This can result in alcohol dependence and a host of harmful health consequences, including painful small fiber peripheral neuropathy. Furthermore, mixing alcohol with certain medications can be dangerous, and the risks of using alcohol to manage pain should not be underestimated.

Alcoholics have a lower pain threshold when sober

Alcohol has been used to relieve pain since ancient times. While it is a common belief that alcohol dulls pain, research shows that sometimes alcohol can make pain worse. Studies have found that alcohol misuse generates painful small fibre peripheral neuropathy, the most common neurological complication associated with alcohol use disorder (AUD). Over time, AUD can also cause nerve damage that results in chronic pain.

Chronic alcohol consumption may make people more sensitive to pain through two different molecular mechanisms: one driven by alcohol intake and one by alcohol withdrawal. During withdrawal, people with AUD can experience allodynia, where a harmless stimulus is perceived as painful. Research has shown that pain thresholds are lowered when chronic alcoholics are sober and pain is induced, meaning they are more sensitive to painful stimuli.

The relationship between alcohol and pain is a complex one. Alcohol can play a role in overdose deaths when mixed with opioid painkillers, as both substances suppress areas in the brain stem that control breathing. However, regular use of one drug can also diminish the effects of the other. For example, in rats allowed to drink alcohol for eight weeks, opioids became less effective at reducing physical pain.

The management of pain in patients with alcohol problems poses unique challenges. Biases exist regarding the cross-tolerance effects of ethanol and opioids and the pain thresholds of patients with substance abuse histories. Patients with a chronic alcohol history will likely respond to pain and opioid medications differently from those without a substance abuse history.

Finally, the phenomenon of conditioned tolerance may also provide insight into alcohol use and pain tolerance. If a patient with a chronic alcohol history has conditioned themselves to self-medicate whenever they feel pain, they will experience lower pain tolerance if they do not receive their drug of choice.

Alcohol increases the risk of overdose when mixed with opiates

Alcohol has been used to relieve pain since ancient times. Laboratory studies have confirmed that alcohol reduces pain in both humans and animals. Recent research suggests that 28% of people experiencing chronic pain use alcohol to alleviate their suffering. However, using alcohol to alleviate pain can lead to harmful health consequences.

Chronic alcoholics are more sensitive to the analgesic effects of alcohol. Alcohol can help them endure discomfort for longer periods. However, tolerance develops to alcohol's analgesic effects, so it takes more alcohol to produce the same effects. This can lead to alcohol dependence and misuse. During withdrawal from chronic alcohol use, pain sensitivity increases, which may motivate some people to continue drinking or increase their alcohol intake.

Chronic alcohol abuse can also lead to the development of alcoholic neuropathy, which causes chronic pain and other symptoms. More than half of people with alcohol use disorder (AUD) experience persistent pain. AUD is also associated with changes in how the brain processes pain signals.

When it comes to managing pain in patients with acute or chronic alcohol problems, there is a debate among physicians. Some argue that patients endure unnecessary suffering due to reluctance in prescribing adequate amounts of pain medication. Others caution that the potential for addiction warrants caution in prescribing narcotics. As a result, patients with alcohol problems may suffer needless pain or self-medicate with illicit drugs, including opioids, which carry serious risks when combined with alcohol.

Opiates are often prescribed "as needed" or "PRN," leading to a constant struggle between patients and medical staff. Inadequate doses of opiates are given, and when patients request more medication, healthcare workers worry about overmedication and addiction. This can lead to refusal or delay in providing the next dose.

Alcohol dependence can lead to painful neuropathy

Alcohol has been used to relieve pain since ancient times. Laboratory studies confirm that alcohol reduces pain in humans and animals. However, using alcohol to alleviate pain can lead to harmful health consequences, including an increased risk of alcohol dependence.

Withdrawal from chronic alcohol use increases pain sensitivity, which can motivate some people to continue drinking or increase their alcohol consumption. Over time, alcohol misuse can lead to painful small fiber peripheral neuropathy, the most common neurological complication associated with alcohol use disorder.

Alcoholic neuropathy is a severe condition caused by excessive alcohol use, resulting in nerve damage. The condition commonly presents with pain, numbness, and unusual sensations in the limbs, leading to reduced mobility and loss of bodily functions. Up to 66% of patients with chronic alcohol use disorder may suffer from alcoholic neuropathy.

The exact causes of alcohol-related neuropathy are not fully understood, but researchers have found that long-term alcohol consumption can damage peripheral nerves. Alcohol can impede the absorption of essential vitamins and nutrients for the nervous system, leading to malnutrition and contributing to nerve damage. Additionally, chronic alcohol consumption can cause oxidative stress and inflammation, associated with damage to the myelin around nerves and important neurons.

Treatment for alcoholic neuropathy focuses on alcohol sobriety and the replacement of key nutrients. Early diagnosis and treatment can improve the outlook for individuals with alcoholic neuropathy, as nerve damage caused by alcohol can be partially or fully reversible. However, if left untreated, alcoholic neuropathy can lead to permanent nerve damage, disability, and chronic pain.

Self-medication with alcohol is a common coping strategy

Alcohol has been used to relieve pain since ancient times. Laboratory studies confirm that alcohol does indeed reduce pain in humans and animals. Research suggests that 28% of people with chronic pain use alcohol to alleviate their suffering. Alcohol increases the analgesic, reinforcing, and sedative effects of opiates, elevating the risk of combined misuse of alcohol and opiates, as well as overdose.

Preclinical studies show that rodents will self-medicate with alcohol when experiencing negative emotional states, such as loss or reduction of an expected reward. Similarly, in humans, the rewarding properties of alcohol increase with repeated exposure, while the aversive properties decline. This can lead to a reliance on alcohol as a coping mechanism, which can transition to problematic use and addiction.

The comorbidity of mood and anxiety disorders with substance use disorders is well-documented. For example, data from Virginia shows that individuals who used alcohol to self-medicate for major depression had increased odds of incident and persistent alcohol dependence. Bipolar 2 disorder had the highest prevalence of self-medication with alcohol, while dysthymia had the lowest.

The treatment for alcohol use disorder (AUD) often involves behavioural treatments and medications. Behavioral treatments involve working with a healthcare provider to identify and change behaviours that lead to alcohol problems. Cognitive-behavioural therapy can help individuals identify feelings and situations that contribute to heavy drinking and manage stress that can trigger a return to drinking. Mindfulness-based interventions can also help individuals develop flexible responses to triggers that prompt drinking. Medications are also available to treat AUD, and these are non-addictive and can be used alone or with other treatments.

Alcohol can reduce pain by increasing gamma-aminobutyric acid (GABA) in the brain

Laboratory studies have confirmed that alcohol reduces pain in humans and animals. Research suggests that 28% of people experiencing chronic pain use alcohol to alleviate their suffering. The self-medication hypothesis posits that individuals drink alcohol to cope with anxiety, depression, and pain. This is supported by studies that show rodents will self-medicate with alcohol when experiencing negative emotional states.

Gamma-aminobutyric acid (GABA) is a neurotransmitter, a chemical messenger in the brain. It slows down the brain by blocking specific signals in the central nervous system. GABA is the most common inhibitory neurotransmitter in the central nervous system. It produces a calming effect and plays a role in controlling anxiety, stress, and fear.

Alcohol increases the effects of GABA by activating GABAA receptors, which decrease neuronal excitability. This activation tends to decrease the excitability of neurons, which results in a calming effect. This is one of the ways in which alcohol reduces pain.

However, tolerance develops to alcohol's analgesic effects, and increasing alcohol use can lead to alcohol dependence. Withdrawal from chronic alcohol use increases pain sensitivity, which may motivate some people to continue drinking. Over time, alcohol misuse can generate painful small fiber peripheral neuropathy.
