What causes numbness on upper back?
Patient: I have a approx. 2 inch by 2 inch area on my upper back, next to my spine on the left side, that has been numb for the last 4 months. I m just wondering if it s something I should be concerned about. There is a mole in that area, but the numb area is bigger than just the mole. Doctor: Hello,  The numbness in the area is due to a nerve related problem. It can be due to a mild nerve root compression. In case the numbness is increasing then do consult a neurologist for proper treatment.   Hope I have answered your query. Let me know if I can assist you further.
