Hello - 2 weeks ago, I was ill with tons of drainage, sore throat, etc.; saw doctor and was told viral - gave me a shot and Rx for cough. Several days later (a week ago Sunday), I went to after hours with same symptoms; diagnosed with sinus infection. Given an antibiotic. Missed a week of work, but started feeling better last Tuesday....went back to work....last Sunday, ate my first big meal and threw up/diarrhea. Thought no big deal. Worked all week; finished last of my antiobiotic Monday. Today, went to work today with a bad headache, threw up, and am now back home. Have taken Tylenol/advil, drinking and crackers but still headache. Is this all related - or something new???? Dr. is booked today so my only option is after hours again....I hate going there. thoughts?
