Thumb arthritis, especially in the CMC (carpometacarpal) joint, is a common cause of pain and limited hand function.A corticosteroid injection can be used to reduce inflammation in the joint, relieving pain and improving grip strength and motion.This minimally invasive treatment is often effective for people whose symptoms haven’t improved with splinting or therapy — and it can delay or even prevent the need for surgery. #arthritis #PainManagement #painrelief | Precision Care Medical & Sports Pe
