Posting for traffic and because I would feel a fraud on the cancer side. I had surgery to remove pre cancerous cells in my left breast in October, it went so well that the treatment finished three weeks ago. But my shoulders and arms ache, my right arm in particular feels tight just below my shoulder . I had a frozen shoulder 10 years ago and it started like this months before it siezed up. Has anyone else had this after breast surgery? Also should I try physio or sports massage to tackle it?
