Hello! My name is Dr. Aida and I am glad to attend you on Healthcaremagic! Considering your clinical situation, I would recommend starting pregabaline or gabapentine to help relieve the burning sensation. You should discuss with your doctor on the above treatment options. I would also recommend performing further tests to investigate for the possible underlying causes (thyroid hormone levels, complete blood count, blood electrolytes, iron levels, etc.). Hope you will find this answer helpful! Kind regards!
