Your toes may feel as though they have fallen asleep even though you have been moving around. Perhaps the bottoms of your feet burn at night, or your hands tingle for no clear reason. If you drink heavily or have been drinking regularly for years, alcohol could be contributing to those symptoms.
Long-term alcohol use can damage the peripheral nerves, which carry signals between your brain, spinal cord, arms, and legs. This condition is often called alcohol-related neuropathy.
Alcohol is not the only possible cause. Diabetes, thyroid conditions, vitamin deficiencies, kidney problems, medications, injuries, and pressure on a nerve can all cause numbness. That is why ongoing symptoms need a medical evaluation rather than a guess based on your drinking history.
What Alcohol-Related Numbness May Feel Like
Nerve damage does not always leave an area completely numb.
It may begin as a faint tingling in your toes. You might describe it as pins and needles, burning, buzzing, or small electric shocks. Some people become unusually sensitive to touch, while others have trouble feeling pain or temperature.
Your feet may feel cold even when they are warm. You might step into hot bathwater and not realize how hot it is right away. A blister or small cut may go unnoticed because the usual pain signal does not reach your brain clearly.
Cramps and muscle weakness can occur along with the changes in sensation. Your legs may feel heavy, or your feet may not land where you expect them to when you walk.
Balance problems are common too. You may stumble in the dark, trip on uneven ground, or feel less steady when climbing stairs. These changes usually appear gradually. They are different from the temporary sensation you get after sitting awkwardly and putting pressure on one leg.
Why Heavy Drinking Can Affect Your Nerves
Researchers do not point to one single cause of alcohol-related neuropathy.
Alcohol may have a direct toxic effect on nerves. Heavy drinking can also interfere with nutrition, which adds another source of damage. You may skip meals, eat very little, or rely on food that does not provide enough of the nutrients your nervous system needs.
Your body may also have trouble absorbing and storing certain vitamins when you drink heavily.
This means two people with similar drinking patterns may not develop the same symptoms. The amount you drink, how long you have been drinking, your diet, your overall health, and other medical conditions may all affect your risk.
Why Vitamin Deficiencies Can Make Symptoms Worse
Thiamine, also known as vitamin B1, may be able to help the nervous system function properly. Heavy alcohol use is closely connected with thiamine deficiency because alcohol can interfere with both nutrition and the way the body absorbs or stores the vitamin.
Low levels of vitamin B12, vitamin B6, or folate may also contribute to tingling, weakness, and other nerve symptoms.
It may sound reasonable to begin taking several supplements on your own. That approach can create new problems.
A daily vitamin will not repair every type of nerve damage, and supplements cannot address ongoing alcohol exposure. Taking too much vitamin B6 can even cause neuropathy.
A doctor may order bloodwork to check your vitamin levels and look for other causes. Treatment should be based on what your body actually needs rather than taking large doses and hoping the numbness disappears.
Which Parts of the Body May Be Affected First
Alcohol-related neuropathy often begins in the toes and feet.
At first, you may notice that two toes feel strange or that the soles of your feet burn after you lie down. The tingling may gradually move toward your ankles and lower legs.
Both sides are often affected in a similar way. One foot may be slightly worse, but the pattern usually does not remain limited to one small spot.
As the damage progresses, symptoms may reach the fingers and hands. Clinicians sometimes describe this as a stocking-and-glove pattern because the affected areas resemble the parts of the body covered by stockings and gloves.
The legs are usually affected before the arms. You may also develop cramps, weakness, reduced reflexes, or an unsteady walk.
Nerves connected with internal body functions can sometimes be affected in severe cases. This may contribute to dizziness when standing, digestive trouble, sexual problems, or changes in bladder function. Tell your doctor about these symptoms even when they seem unrelated to the numbness.
May Cause Similar Symptoms
It is easy to blame alcohol when you already know you have been drinking too much. The cause may be alcohol, another condition, or several problems happening at once.
Kidney disease, thyroid disease, autoimmune conditions, infections, liver problems, and spinal conditions can also affect sensation. Some chemotherapy drugs, seizure medications, and other prescriptions may cause nerve damage.
Pressure on a single nerve creates a different pattern. Someone who passes out or sleeps heavily while intoxicated may remain in one position for hours. The pressure can injure a nerve and leave one hand, arm, leg, or foot numb or weak.
That type of problem may affect one specific area rather than starting in both feet. It still needs attention, especially when weakness does not improve after changing position.
Sudden numbness should not be assumed to be neuropathy. Call 911 if numbness appears suddenly on one side of the body, particularly when it occurs with facial drooping, trouble speaking, confusion, severe dizziness, or weakness. Those symptoms may signal a stroke.
