What causes severe cramping in thenar muscles on clenching fist?
Patient: When I use implements that are held in a clenched fist, like a spatula or hammer, with a firm grip, I get severe cramps in the thenar muscles. What is going on, and what are some good massage or stretching techniques to relieve the cramps and is there anything I can do to make this occur less frequently? Doctor: Hello,Any medication you are on, I can infer that you get frequent cramping. I would suggest you to get your VIT D and VIT B12 levels done. If theses are low then to take supplements to normalize these levels. If even after taking these supplementation if the symptoms persist then to consult a orthopedic doctor.Wishing you a speedy recovery. Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Santosh S Jeevannavar, Orthopedic Surgeon
