Thanks for posting your query.
From description it seems pain in shoulder and arm is due to pinched nerve
If there is no relief with physiotherapy
, get a MRI
done under guidence of your orthopaedic to see any disc bulge causing compression over nerve roots. In this case surgery (disectomy) is another option to decompress the nerve roots.
Hope this will helps you.
