The last couple of days I have woken up with hot sensation and very minimal sweat feelings in my forehead that last less then 30 seconds... then it goes back to normal... The heater its also high in the room and It wakes me up every 2 to 3 hours and it happens when I'm having what it looks to be nightmares... Also swollen lymp glands underneath the jaw... What Can this be?:confused:

Sounds like you have a fever, made more uncomfortable by heat set too high (why can't you turn it down)?
Lymph glands get swollen when your body is fighting infection.
You could have just about any condition, so get to a doctor.
Tooth abscess, mastoiditis, mono, who knows, the list goes on.

Oh also I had one of my wisdom tooth on the right side of the mouth cheked out on August of last year because It cracked and I was in extreme pain. The dentist told me to either do a rootcanal or pull it out. I took antibiotics for the pain and it went away.. she told me that it was an infection in the moller. I haven't done anything about it since then and now I see a red bump right next to the tooth on the gum and it goes down when I don't eat and it rises up when I do it

Tooth problems don't always hurt at the tooth. Get thee to a dentist, or an oral surgeon, who is the one I would go to for extraction. Not all dentists do a good enough job with them. It's not as simple as reaching in with pliers and yanking, because the tooth usually breaks.

Could that explain that I might have in infection from the tooth and why my lymp glands underneath my jaw are swollen? And having a fever sensation like a hot flash
