After six weeks, the virus is no longer causing your symptoms (unless you have an impaired immune system--AIDS or something like that.) You've gotten a bacterial infection somewhere in your respiratory system (sinuses/lungs). Will you get better without antibiotics? Eventually. Like maybe next May. But why not just phone your doctor and ask for a prescription of Zithromax (or whatever antibiotic your doctor prefers) and feel better in 2 days? Why are you suffering over something so simple to cure?
