My uperarm muscles are aching constantly my left arm ive had rotator cuff surgery turned in ti frozen shoulder over a year but still hurts?

C spine stenosis: have you had a cervical spine MRI? This might be a form of "sciatica" from a pinched nerve in the neck.

Ortho evaluation now: Chronic pain after rotator cuff surgery manifested by frozen shoulder (adhesive capsulitis) can happen, especially in women between 35-60. If appropriate nonoperative management has failed to help for a year, you may need further surgery. Seek evaluation by a sports medicine trained orthopaedic surgeon who specializes in shoulder injuries. Advanced imaging (MR arthrogram) may be indicated.
