You could consider an EMG/NCV test of your nerves. This could identify if the disorder is radiculopathy vs thoracic outlet syndrome vs brachial plexopathy. A detailed physical examination by an experienced specialist (rare) can discern the disorder but an EMG test and/or a shoulder MRI can be helpful.
