Darkpowder, i had the same issue as you. keep taking the antiflammatories and rest it wil lhelp big time. when you can start back training try not to just focus on crush strenght (grippers) work on the other areas of your grip, pinch, support, open hand, wrist. it will help as it strenghten all the different muscles involve on gripping.
Ironmind is a good source to learn about grip strenght.
