Mostly its in my right hand but I am consistently getting a muscle type cramp in my hand and into my fingers. It feels like a Charlie horse or muscle spasm that makes my middle finger and thumb almost lock up and I need to stretch them out until it goes away. Ive been trying to drink lots of water but it doesn t seem to be changing anything. Should I be concerned? I m 47 and in good shape. I did break my neck twice in the passed but have been told I m recovered from those injuries which the first time was in 2001 and the second was three years ago.
