Mabey you should find out.

Peace you are spending too much time fixated on your body's conditions which are normal. so you had a viral infection that resolved itself after 21 days -again, normal!

try to focus your attention on something more positive and put away the thermometer. Doctors do not consider your temperature readings abnormal. Weight loss, throat clearing, etc: I'd get your thyroid checked.

Clearing your throat is very common. Everyone does it several times per day, so it may not be a symptom. If you have GERD, then you should stay on the PPI (pantoprazole) for at least a month. Prevacid is over the counter, so go ahead and get some. Also, place some books under the legs of your bed, but only at the head. This will raise your head while you sleep, making GERD symptoms better. It'll take several weeks for things to heal up. Also, extra pillows don't work for most of my patients, simply because it is too easy to roll off of them at night.

But with the limited info here, I'd put my bets on hyperthyroidism. Best of luck.
