Hi- I got switched from anastrazole to examestane about ten days ago, I already have rheumatold and osteoarthitis but getting joint pain from hell, especially in wrists and hands, and now feet. also horrible muscle pain. saw surgeon yesterday as pain in sternum and ribs on opposite side to my surgery. feeling really down, he is being cautious so has referred me for both CAT and bone scans to check out whats going on my anatomy is weird due to birth defect in chest, born with what I now know is Polands syndrome, missing pec muscles and sternum is depressed, so ribs on right side go in instead of out. Also, breast didnt develop properly so had an implant removed when they gave me mastectomy and reconstruction, anyway, I feel really awful physically, and emotionally. I dont like the look of what Im left with, the dent is horribly obvious, I have a dog ear scar that sticks out like a hump on my side, and other scars down side of breast are a right mess - he was joking that during surgery he thought about putting in an implant to fill the dent, then putting another one on top of it to make the mound, I rather wish now that he had done so. Im dreading that there may be bone issues ok, scared its cancer in my bones, although mine was stage 2 invasive ductal and oestrogen positive her negagive. I have an automimmune problem anyway so have been living on methrotrexate and steroids for q17 years, Im sick of being sick, and just want some idea of what to expect from the bone scans. I know I need to get used to the exeamestane, but wonder if I can cope if thats whats causing so much pain, esp. in ,y hands and wrists, my work involves writing or typing and I can barely hold a pen.
