I have been on tomoxefin since June. For the first 3 months I had terrible hot flashes and no period. After 3 months of hot flashes they went away thankfully. Then at the end of October the hot flashes returned. Shortly after that I had a period. I have been having regular periods since then. I always start with the hot flashes a few days before my period and a few days after. but this month has been so different. The hot flashes are worse than ever and I have night sweats so bad that I can't sleep. I feel so tired all of the time. My period stopped two weeks ago and the hot flashes are still happening. I fear that it's because my hormones must be doing something crazy and it's going to make my cancer return somewhere. I had a double mastectomy but I have been having pain under both arms and in my left breast(the one that didn't have cancer) Also my allergies acted up really bad before I was diagnoses. My allergist said there is a direct coorilation between hormones and allergies. And now, even in the middle of winter my allergies are acting up. It just sucks because I have no idea what is going on inside my body. All they tell you to do at this point is to look for symptoms....not all cancers have symptoms. Maybe what I am experiencing now are symptoms?? anyone ever experience any of this?
