I have been having rib pain now since the start of Nov 13. Have tried chiropractor but been unable to resolve. Chest xray showed some shadowing but I don t know of what. Previously had breast cancer, lumpectomy 20 months ago but lymph nodes OK. Gp has said to have further xray in 1 month but its driving me mad and keeping me awake. Was on tamoxifen but stopped as little benefit in my case. Tamoxifen forced me into menopause straight away. No previous signs of menopause although I m now 55. Had no period now for 10 months but started bleeding on 3rd Feb which has been ongoing although I think it may be slowing. Gp says its perimenopause so not a issue unless period has stopped for over 12 months. I m just starting to get pain/discomfort from it together with the rib pain is now making me feel real grotty. Any suggestions?
