I occasionally feel a full body flush where I burn on the inside with different intensities. It always seems to happen 3-4 hours after I have been asleep. Last week it was just my legs and happened in the morning. I had a total hysterectomy 8 years ago. It is scary. I have anxiety issues so I have to be careful not to freak. I turn on a fan on high to blow on me, I put a cold washcloth on my head, i do deep breathing, I take 2 aspirin, and one klonopin. This can last anywhere from 20minutes to 2 hours or so. I never know when it will happen or what triggers it. Can anyone telll me what is happening or if they have gone through this before and what they do about it? Thanks, Mary
