Hi, I am a 51 year old woman, reasonably healthy, but have gained 15 pounds in five years and I am 4'10" -- for last 10 days I have experienced persistent tingling in my left hand and now it is in my arm. I am getting worried...I have a family doctor but I don't really like him and have ignored this (was on vacation), now think this might be something. I spend much much time sitting at a desk and typing ... what could this possibly be and what is your advice? Thank you, whoever you are, for responding.
