Uh... how long have you had this? When does it come and go? Is it constant throughout the day or just for a little while then stops?
Details please!

its been goin on for about 4 days now it comes and goes quite often..ive had a full hysterectomy and am menopausal....dont know if my blatter is leaking inside or what it is but it is a wierd feeling .....its a very warm flushing

I've had a warm flushing sensation in my back for about two months now, about the same time I've been off birth control pills. Lately, I've been experiencing it in my arms, legs, and butt. I was on the pill for 17 years; I'm wondering if my body is reacting to getting off of them.
