In the palm of each hand, the area between the bottom of my thumb to where the hands connect to the wrists, cramp sporadically, not related to any particular use or movement, nor temperature. The areas do not feel hot or cold. On occasion, the areas appear to be blue. Stretching relieves the sensation. I do not engage in repetitive tasks. The only other cramping is in calf muscles and feet on occasion. WHAT is this? It began last year when I was using hand weights, which I stopped 5 months ago I am 56.
Dear Sir/Madam have gone through your query and read your symptoms. In my opinion, these are muscle cramps in the hand muscles, of your thumb, watch for calcium level and It B 12 level, also It E deficiency has been found to cause cramps, ask your doctor for tests and see if you are suffering from any such thing. I hope that answers your query. If you want any more clarification, contact me back.
