Sounds like you had influenza and a secondary bacterial infection of the sinuses and that is why the doctor prescribed the antibiotics.
Influenza affects makes you feel ill all over.
At a temperature of over 104, you should have been in hospital. That is very seriously high.
I am glad you are better now.
I am fully recovered now. The antibiotics seemed to have done the trick, because the fifth day on my last one I felt noticeably better. I think I may have had a sinus infection but I think I also had another form of infection, which caused my stomach queasiness. Pepto Bismol and saltine crackers also helped! You are probably right, I should have gone into the ER, but I try to avoid that whenever possible. Thanks for the feedback!
I had the flu recently and it lasted about 5 days. My fever only reached 102. 105 is very serious and you should be in the hospital.
I m not a doctor but i dont believe your symptoms are from a simple sinus. A lot of reasons might be causing your symptoms and is very difficult to get a diagnosis over here so please visit again the doctor or another doctor to get a diagnosis
