I recently began experiencing some tingling in my right thumb. The consequence of this is that I m not as able to do routine things such as buttoning the left hand cuff on my shirt or exerting leverage to open a food package using my right hand. I live in Chicago, and the weather here has been quite cold which may explain the limitations in my thumb s functioning (altho I ve lived in this climate for nearly 30 years). I take a beta blocker for my heart and Celebrex for arthritis in my knees--also, a statin drug to control cholesterol. I worry that the sudden emergence of this stiffness/tingling in my thumb may suggest the beginning of some other condition. I am a 77 year old male in good condition, weight 190 lbs. I d appreciate your thoughts.
