I can not bend the last joint closest to end of thumb without joint catching and locking into the down position. When trying to bend that joint the pain runs down the thumb. Have had no trama to thumb the clicking of the joint started as mild and has worsened over the last month.
Hi, Thank you for providing the brief history of you. A thorough musculoskeletal assessment is needed. As you have pain at the base of the thumb and while flexing the thumb the pain is arising, it could be due to tenosynovitis. For this, pain, you can under physical therapy like - therapeutic ultrasound therapy and TENS therapy. Also, using the thumb splint for 2-3 weeks should provide good stability. Besides, the therapist will teach some physical exercises to be performed for the correction of the biomechanic of the muscles. RegardsJay In Chat Doctor.
