I m having numbness in my fingertips on both hands periodically, this has been the case for approx. 2 months thus far, and I m concerned about what could possibly be the issue. I had a rapid weight gain this past year, which is not at all like normal, since most of the time my weight has been steady. I was at around 245lbs and now am at over 280lbs (6 4 tall). I am 58 years old, and have had annual physical examinations every year, where things have improved except for this past year. I have never been diagnosed with having diabetes, and have had my blood tested before my annual physical. Can you please give me some advise as to what I might be dealing with, and should I be concerned?
