I Developed A Seriously Bad, Double Ear Infection After I

I developed a seriously bad, double ear infection after I caught a cold in May. I didn't know I had it, until I went to the Dr in Aug. (no pain until then.). then with meds, it cleared up but I got a sinus infection. so with more meds, that cleared up and then I was referred to an ENT. I told him things taste funny. Dairy, yogurt, carbonated sodas, BBQ sauce and other stuff. things smell equally as bad, perfumes, deodorants, soaps, etc. more on the pesticide or vitaminy kinda small. now my left ear kinda hurts again, but everything is clear and things still taste/smell aweful. any suggestions?
