In 2004 I had reconstructive suregery for breast cancer (DCIS) I had a total of 8 operations and problems with my shoulder ever since. An xray showed impingement & the consultant asked me if I had ever broken it which I have not. He asked again Are you sure you ve never broken it or dislicated it? I am a gymnastics coach & had previous muscle issues but no where near as bad as it s been for 8 yrs ~ burning sensations & pain laying on it or with continuel use. The consultant showed me a shadow in the bone & requested an MRI which I still havn t had. I return to see him on 15th Dec. He didn t tell me what it was just said he would sort it when he does the impingement surgery. I am worried it could be cancer as my cousin went on to have bone cancer after she had breast cancer. I also suffer daily chronic headaches (5 yrs) & recently diagnosed with degeneration of the neck and degenerative disc disease in my lower spine requiring surgery. But I am anxious to know what this shadow could be?
