I am 64 an way pass menopause, but last tuesday I woke up 3 times n 2 hour's time , sweating , face flushed red, weak , upset stomach, so tired it was like I hadn't had any rest. 8 day's later an it's still going on.Went to urgent care an they gave me Azithromycin 250mg, an a shot, did this on sat. past but I am still feeling as bad as I was from 8 day's ago. . What is going on with me? , it's really starting to scare me, don't smoke or drink either.Should I be really concerned, I am so afraid of a heart attack, an yes I am over weight, have lost 10lbs in 8day's.
