Tweetyes I definitely would do as baby and MM have suggested . and go be seen by your Dr asap. its hard to believe there so many muscles in the forearm. and underlying muscle we don't even see.
I hope we all have helped you somewhat. the Dr will perform a grip strength test probable . have you squeeze his fingers , also have you try pushing upward as he pushes down on the back of your hands. he might actually give you a device to measure your grip strength. I had this also when at physical therapy.
