I have a below normal temp.....mine is usually 97.1 and it's been below this for several days like 96.6, then it goes up to maybe 98.8 and I feel lousy......i thought it was a sinus infection starting, but now it seems to be into my chest.....coughing a very dry, shallow cough.....a bit of an earache and sore throat, headache, just no energy.....should i go see my Dr and see about an antibiotic? Also, wondering if maybe allergies can cause these kind of things to manifest....i am allergic to so many things.....everything but cats! thank you
