STUDY: ALCOHOL RELIEVES FIBROMYALGIA PAIN

Study: Alcohol Relieves Fibromyalgia Pain

Another study is adding to a growing body of evidence that alcohol is an effective – yet risky – way to treat chronic pain.

Researchers at the University of Michigan surveyed over 2,500 patients being treated at a university pain clinic about their drinking habits, pain severity and physical function. Participants were also assessed for signs of depression and anxiety. About a third of the patients were diagnosed with fibromyalgia (FM), a poorly understood disorder characterized by widespread body pain, fatigue, insomnia, headaches and mood swings.

Researchers, who recently published their study in the journal Pain Medicine, found that patients who were moderate drinkers had less pain and other symptoms than those who did not drink alcohol.

“Female and male chronic pain patients who drink no more than 7 and 14 alcoholic drinks per week, respectively, reported significantly lower FM symptoms, pain severity, pain-related interference in activities, depression, anxiety and catastrophizing, and higher physical function,” said lead author Ryan Scott, MPH, of UM’s Chronic Pain and Fatigue Research Center.

“These findings suggest that chronic pain patients with a lesser degree of pain centralization may benefit most from low-risk, moderate alcohol consumption.”

According to the Mayo Clinic, moderate alcohol consumption for healthy adults means up to one drink a day for women of all ages and men older than age 65, and up to two drinks a day for men age 65 and younger.

Of the study participants, over half reported use of opioid medication, which carries serious risks when combined with alcohol. Perhaps for that reason, participants in the UM study drank less alcohol than the general population.

“People with chronic pain may drink less due to the stigma and because they are being told not to drink while on pain medication,” says Scott.

Moderate drinkers with chronic pain were more likely to be white, have an advanced degree and were less likely to use opioids. They reported less pain, lower anxiety and depression, and higher physical function.

Researchers found that fibromyalgia patients who drank moderately reported decreased pain severity and depression, but alcohol had no effect on how widespread their pain was or other symptoms such as cramps, headache, fatigue, poor sleep and cognitive dysfunction.

Scott believes alcohol may stimulate the production of gamma-aminobutyric acid (GABA), a neurotransmitter in the central nervous system that reduces nerve activity. Alcohol and drugs such as gabapentin (Neurontin) that act on GABA typically have relaxing effects.

“Alcohol increases gamma-aminobutyric acid in the brain, which is why we could be seeing some of the psychiatric effects. Even though alcohol helped some fibromyalgia patients, it didn’t have the same level of effect,” said Scott. “You probably need much more GABA to block pain signals and that may be why we’re not seeing as high an effect in these patients.”

Over a dozen previous studies have also found that alcohol is an effective pain reliever. In a 2017 review published in the Journal of Pain, British researchers found “robust evidence” that alcohol acts as an analgesic.

“It could be a stepping stone to increased quality of life, leading to more social interactions,” says Scott. “Fibromyalgia patients in particular have a lot of psychological trauma, anxiety and catastrophizing, and allowing for the occasional drink might increase social habits and overall health.”
