A burning sensation in the feet and legs are reasonably common and can be caused by many different things, that are sometimes hard to diagnose.
This is a condition that affects the peripheral nerves in the legs. It can result from various underlying causes, including diabetes, vitamin deficiencies, certain medications, alcoholism, infections, and autoimmune diseases. Peripheral neuropathy often leads to tingling, numbness, and a burning sensation in the legs and feet.
When nerves in the legs or feet become compressed or pinched, it can cause a burning sensation. For example, herniated discs, sciatica, and tarsal tunnel syndrome (compression of the tibial nerve in the ankle) can lead to nerve compression and subsequent symptoms.
Reduced blood flow to the legs and feet can cause a burning sensation. Peripheral artery disease (PAD), atherosclerosis (hardening of the arteries), and blood clots are common causes of poor circulation.
Restless leg syndrome (RLS):
RLS is a neurological disorder characterized by uncomfortable sensations in the legs, often described as aching, tingling, or burning. People with RLS usually experience these sensations when at rest, such as during sleep or sitting for extended periods.
Deficiencies in vitamins like vitamin B12 and vitamin D can contribute to nerve damage, leading to a burning sensation.
Often times there is no identifiable cause or it is not yet apparent. This can be called Grierson Gopalan syndrome.
