I am 65 and for months I have been having what I think are night sweats in my groin area. The problem is bad enough that I wear a a heavy pad so I don t get the bed sheets or my night clothes wet. But I am not sure it is sweating because it has a strong urine smell when I get up in the morning. I get up at least twice a night to urinate. This seems to be worse if I take any kind of pain medication or sleep aid such as ambien. I had breast cancer last summer diagnosed as DCIS and had a left breast mastectomy. I am now on a medication called Arimadex for 5 years. The cause of the cancer was too much estrogen. Could I have some kind of infection or more serious problem?
