I'm a 77 year old male. For 8 days now I have been sweating on my forehead, back of neck for no reason at all. The sweating can happen at any time during the day or night. I'm not doing anything unusual nor am I eating anything unusual while this happens. I also get woken up at night with sweats. The sweating is not constant. So far I have been sweating about 10 times in a 24 hour period and each episode may last anywhere from 5 to 10 minutes.
My doctor took blood test, chest xrays, EKG, urine sample, and a culture test, all tests did not indicate any problems. I had my PCP and the emergency room doctor check me out, both doctors said that there is nothing wrong with me. I also get a bitter taste in my mouth along with the sweating. I'm nervous, doctors don't have given up on me, they said that they don't know what else to do. PLEASE HELP!
