Tingling And Numbness In The Right Hand And Pain In Shoulders

Hello I have been experiencing tingling and numbness in the right hand, mainly thumb, forefinger and middle finger, for the past three weeks. Also experiencing pain in the shoulder, mainly the Teres minor and/or Teres Major (difficult to tell), Infraspinatus and Supraspinatus. Some restriction but little pain in the upper trapezius area, or more likely in the levator scapulae. I am feeling extremely slight tingling sensation in left hand and fingers, but so slight it is hard to tell whether I am imagining it. I am right handed. Neck flexion to the right causes tingling in the hand and pain in the Teres Minor/Major region and the Infraspinatus. Rotation to the right causes slight pain in the same areas, although rotation and then flexion (looking down and back over my right shoulder) causes strong pain. No pain/restriction going to the left. Weakness in the arm/deltoid is experienced when doing a push up/bench press and tricep dip. Weakness in the shoulder when doing a lateral and/or forward straight arm extension (palm down). No weakness in bicep. There appears to be no supination weakness. No difficulty straightening the arm. Re potential Carpal Tunnel, there is no pain in the wrist or hand and there appears to be no loss of strength in the hand. No difficulty tilting wrist backwards. Forefinger has odd sensation of feeling like it needs to be “cracked” at he main joint. No increased numbness/tingling when flexing the hand forward and holding for 60 seconds. Slight forearm muscle atrophy (but more likely attributable to decreased exercise). Existing conditions include potential “slap tear” in the shoulder, weakness of the rotator cuff, and “dead arm” sensation when throwing a ball or serving at tennis. An MRI scan shows I have damaged cartilage in the wrist due to a fall 16 months ago (underwent arthroscopic surgery on the left wrist 9 months ago to clean up tear to scapholunate ligament and remove extensively damaged cartilage so there is potential for similar condition in the right wrist.) General posture is reasonable, with slight forward pelvic tilt. Activities around the time the condition presented: hard throw of a cricket ball (weight 5.6 ounces) caused severe dead arm and pain; for a number a weeks prior had been painting inside of house, climbing ladders and stretching and twisting at different angles; changed to a new office at work (similar but different chair and desk height and desk set up similar). I have received physio treatment, mainly working on the neck, with some mobilisation. Remedial exercise: rotating head to the left then looking down over left shoulder while extending right arm and bracing against wall. Neck treatment has seemed to make little difference whereas massage on shoulder and median and radial nerves on the shoulder and forearm have lessened tingling symptoms slightly. Lyall Johnson
