I am 36 years old and for the last few months I have been running consistently hot. Night Sweats are common. After I get out of the shower in the AM it can take me up to 2 hours to cool off. I usaully start sweating in my upper body first. My fiance and I constantly fight about the temperature in the house because I keep it too cool for him. Surely I cannot be menopausal?
I am going through menopause and this sounds exactly like hot flashes--but, because of your age, I would have this checked out by a doctor before I would accept the idea of menopause.
