I am almost 57, this week. I had a total hys over 10 years ago. Have been on antid way before that after a miscarriage, stresses in new marriage. I have sever problems sleeping for over 10 years also. Tried many different prescription drugs. I have not been on any hrt in a couple of years, haven't had a hot flash in a long, long time. Past six months I have had what I thought were sinus infections. Went to doc and was treated for that and symptoms of headache (whole head), fatigue, "swimming" head feeling and would feel good for a month or so. Two months ago I started having hot flashes again??? Went to doc yesterday and decided to order CAT scan, but not sure if my insurance is going to allow it. He tried me on a new sleeping med, trazadone -- didn't do anything. I was awake all night. I can take one ambien and nothing, but two knock me out. Can't do that either when grandkids are here. I don't drink caffiene after noon. I am at my wit's end on why I can't sleep like a normal person, and the hot flashes all of a sudden. Head hurts constantly. Depression is under control. What is wrong with me??
