question: I m a healthy 60yr old woman, & actually just had a recent checkup, but this is the 2nd time I ve experienced this symptom: both arms, especially elbows down, suddenly felt all tingly, & started to shake! Totally unnerved me! I just got home from grocery shopping,& chalked up the feeling to carrying heavy bags! Then I thought-maybe it s low blood sugar (sometimes I get shaky ), so I just had some orange juice & feel better. But my hands still feel strange. I m a real estate salesperson. Circulation problem? Please advise, thanks.
