Hi Robin,
I'm wondering what cased this , your job? a specific acute injury?

Some with thoracic outlet syndrome {TOS} get a clawing and wasting of the hand.
Sometimes there is a definite compression or impingement at the elbow or wrist as well as up at the upper junction {neck/shoulder/collarbone etc} - that can be a case of double crush or even triple crush if all 3 areas are involved.

I just want to mention this because some w/TOS in the past had the ulnar surgery and it did not address the proper cause of the symptoms.
Their symptoms were not really coming from the elbow they were referred pain from higher up.
Do you also have neck, shoulder or upper back pain & tightness?
