There are several causes of peripheral neuropathy in the foot and ankle. Most common is diabetes. Diabetic neuropathy occurs due to prolonged uncontrolled blood sugar. This leads to the destruction of nerves in the foot.
Similarly, prolonged exposure to the ethanol in alcoholic beverages can be toxic to the nerves in the foot, leading to a condition called alcoholic peripheral neuropathy. The nerve tissue suffers damage, which causes burning pain and a lack of sensation. Low back trauma, narrowing of the spine, and clogged arteries can also be causes of neuropathy.
There are several treatment options for peripheral neuropathy
Treatment involves keeping blood sugar levels in your target range. This will not cure the nerve damage, but it can help keep the damage from getting worse, and the pain might get better. Other options include:
Certain oral medications to ease any burning pain
Galvanic Stimulation (which is the therapeutic use of electric current, particularly for stimulation of nerves and muscle)
When you have diabetes, you could have a sore or other foot problem without noticing it. Check your feet every day. An untreated problem on your foot can lead to a serious infection or even amputation.
Be clear with your podiatrist about what is helping you feel better and what is not. You and your podiatrist can work together to find the treatment that helps you the most.
