Hello Thanks for writing to us. What you have described fits into the typical description of hot flushes . It is a signature symptom of peri menopause. Sometimes, period changes might not occur, and some other symptoms might appear before menstrual irregularities set in. There is one objective way of confirming whether this is indeed the case. Please have estimation of the hormones - FSH, LH, serum estradiol. This will conclusively establish if menopause is setting in. In case these hormones are in the normal range, other rare causes for this symptom can be looked into. Take care.
