Hi, I Recently Have Begun Noticing That The Back Of

Hi, I recently have begun noticing that the back of my right hand hurts every time I shake hands with someone. I also have significantly decreased strength in my left arm. I type repetitively and have concerns about carpal tunnel syndrome, but I don't have any of the other common symptoms. My mom has arthritis, however, and a personal history of heart disease. I'm a 37 year old woman, 5'5", 195 lbs with 3 kids and a full time desk job. What should I be asking my doctor concerning this? Any insight is certainly appreciated. Thank you.
