Hi doctors, after recovering from covid, I am having burning sensations under my feet and on my palms. Earlier it was only during night, now it's there throughout the day and worsens at night. Sugar levels, B12 levels are normal. Also experience pain at back of my head, radiating to the neck. Consulted drs n tried nervigen plus, trigabantin 100mcg but it's not helping. Could anyone provide a suggestion? Thanks
