question: I had total knee replacement 2 weeks ago. I m getting little sleep because of the terrible night sweats I ve started having. They did a urine test for infection no results yet. I talked to my pharmacy to see if my meds or any combinations of my meds would cause this. Answer no. I am 69 female. They think my hormones are messed up, which they say happenes sometimes after surgery. What are they talking about? I am going to the Dr. tomorrow looking for answers. This has been a very hard 2 weeks. I have bowel problems, told them and they still did not help me. When through a mess getting them going. Had trouble with med. Now these sweats. Hard to do therapy when tired.
