I had the same exact thing. It lasted for 2-3 days with the leaky faucet shit. I took allergy spray and so on before figuring it out... sinus infection.
Only thing that stopped it was antibiotic. 500 mg of amoxacilin, and continueing to take my allergy medicine. Cough sucks. Still coughing shit up, but it's not REMOTELY as bad since starting the antibiotic day three. Sucks when it wears off and cough comes back. Odd how that works, but it does. Normally an antibiotic would be just giving your the shits.
I'm guessing it's more like boncitis, but they claim sinus infection. Had it for a week now. Still not gone, but much better than the faucet bullshit.
