Hi Friends, My diagnosis was Invasive Mucinous Carcinoma grade 2, had a lumpectomy and 3 titanium clips planted and Sentinal node biopsy. My rib pain started 2 weeks after finishing 21 radiation treatments, making that since early February 2014. First site was under the treated right breast, pain of feeling deeply bruised. By April I had swelling from fluid, pinkness on the breast and more rib pain on my side and above my right shoulder blade. I was checked by ultrasound and x-ray with nothing found and I was advised by my surgeon and GP that it is all radiation damage. It is worrying because I keep feeling the pain is so like pain from a kick to the shin that it should be getting better.. But it that goes on and on, can't lay on that side at all now and am now not wearing a bra as the pressure is too much. I purchased a new long line bra but it still wants to roll up and put increased pressure on the ribs. I am having massage for the fluid, have tried Panadol Osteo and Voltaren without relief. Anyone else experiencing this side effect of radiation that no-one tells you might happen? I was told about the possibility of a broken rib but not this rib pain! Thanks for allowing me to unload.
