What causes numbness in fingers?
Patient: This morning I had numbness and tingling in the fingers on my left hand, it lasted for about 4 hours. I am now experience the same sensation in my lower lip on the left side. I am 29, do not smoke or use drugs, occasional glass of wine. I recently had my bloodwork done and it all came back within normal range. My mother has MS, not sure if this could be related in any way. Doctor: Hello,The feeling of numbness that you are having can be related to electrolyte disturbances or decreased fluid intake. You need to get your electrolyte levels and serum Vitamin B 12 levels checked and start with proper supplements accordingly.Hope I have answered your question.
