I had a total hysterectomy approximately 11 years ago. For the last 6 months or so I will for no reason breakout in a drenching sweat. This can occur during the day or night. I have checked my temp and it is always slightly below normal. It is embarrassing to have sweat running down my temples and a sheen on my forehead from perspiration as well as having damp clothing. I have had blood work done during this time and everything has been normal.
