symptoms: seems to be mostly in my head right now....sinuses...dizzy...left ear very sore....eyes and eyelids are swollen. hard to breath. it came on very fast. the clinic NP said no signs of bacterial infection so they did not give me any antibiotics...said I had Sinusitis , but I ve never felt so bad, not just in my head but all over my body. blood pressure & heart rate races occasionally. bouts of diarrhea and stomach upset. I still have an appetite but certain foods make me dizzy and increase my diarrhea. my concern is possible diabetic? otherwise I am 64 yrs old, very healthy, very active, still working, no meds of any kind... don t drink, smoke 1+ pk cigs per day...weight around 165 but solid muscle. very scary for me. What to do?
