Out in sympathy

Hello there, Just thought I'd share and ask... Since my mastectomy to my left breast at the start of May, my mum passing in conversation has mentioned her left breast has ached. Then at the of August, she was staying with me whilst I had my last chemo session. One morning she came into me and said " ever since your mastectomy my left breast has gone-out-in-sympathy, I've had this rash under my breast". I said you're crazy, have you changed your washing powder, your bra or anything? No, nothing. Was her reply. There was a serious red rash under her breast. Has anyone else experienced such an encounter? Enjoy, Karen
