Be careful with these grip strength thingies. If your finger tendons are overworked, using those will exacerbate the problem. I tell from experience. It’s brutal. Tendons aren’t muscles, they don’t fatigue and recover in the same way as muscles, like from doing forearm curls.

I had a lot of pain, started stretching my fingers and it was gone in a week. Can recommend.
