Hi all, has anyone had a reaction from their tissue expanders that have been put in post mastectomy?? My symptoms are that I have these hot flushes especially following doing minimal tasks. Like showering. I feel nauseated or vomit if I don't take tablets. I also feel like I will pass out. I am on hormones for hot flushes so not my age! My dr ? Reaction from silicon covering of expander but surgeon and physician don't think it is cause. Wondered if anyone had these symptons. I also don't have temperatures recorded. Feeling very ordinary. I was very good for a week post op then down hill since!!! Lozza.
