OK-I just spent 4 days last week in a horizontal position with pretty much the same symptoms that you had. I was tired, my body was sore, and my throat was so sore that I could barely even swallow or talk. I finally broke down and went to the DR, where I too was swabbed for strep throat because my throat was swollen and red. The test was negative. I was also swabbed for the flu. Guess what?!?! It was positive. I really did not have any sniffles or anthing like that. I just laid on the couch and did nothing. The DR did give me an antibiotic for an infection that he <thought> I might have in my sinuses too. Now, I was told that it would take about 7-10 days for it to run its course. I have 2 small children, a job, and laundry! I do not have 7-10 days to spare!!!! So, I followed this regimen and immediately began to feel better. Took my antibiotic as prescribed. Every 2 hours, I gargled with warm salt water, drank a full glass of lukewarm water (didn't want to upset my stomach), and did a "steam treatment" on my sinuses. Basically, I got a kitchen towel, soaked it in hot, steamy water, and without wringing it out, placed it over my mouth and nose and breathed in the warm steam. I also placed Vicks vapor rub over my chest and throat and slept with a warm heating pad over my chest while I got lots of rest!!!! I also added Mucinex which worked wonderfully. Less than a week later, I am feeling pretty good. Still have the cough but at least I am not in a horizontal position anymore! Good luck to you!
Oh, 1 other thing, I did take Ibuprofen for the body aches!
