You could have burning feet syndrome (BFS).
You should see a neurologist to have electrophysiological studies (nerve conduction velocities, electromyography or nerve biopsy) and MRI to rule out peripheral neuropathy
and multiple sclerosis.
General treatment for all cases of BFS includes reassurance about the benign nature of the disorder. Wearing open and comfortable shoes, especially those with arch supports, and wearing cotton socks is
helpful. Soaking the feet in cold water (not ice cold) for around 15 minutes can bring symptomatic temporary relief. Avoidance of feet exposure to heat should be advised. Tricyclic antidepressants
or membrane stabilising agents such as carbamazepine
or gabapentin may be used for symptomatic relief.
Local application of capsaicin ointment and percutaneous nitroglycerine therapy may alleviate pain
and burning. If BFS is due to flat feet, orthotics may help restore the foot’s arch. If inflammation of the nerve is causing the compression, nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed. In patients where pain is not relieved by NSAIDs, local injectable steroids may be beneficial. Surgical
decompression to relieve nerve entrapment may be needed if conservative measures fail.
