I understand your concern and like to answer about it. Your symptoms partially match up to Thorasic outlet syndrome how ever there lies even other possibilities like Frozen shoulder
. If i would be treating you i would suggest you too have a Colour doppler of right subclavian artery
and vein, Chest xray with neck and other routine investigation. Electromyography
would be a next test once the investigation shows a thorasic outlet syndrome. It is treated by cutting the Scaleni mucle fiber and first rib/cervical rib
It is hard to come to a conclusion without the investigations and a clinical examination.
Hope my suggestions are helpful for you further followup. Feel free to ask any further question if you have.
