Maybe try nasal irrigation- gentle and safe. Cleared my infected sinuses.

Yeah, I have. All my life I had one sinus issue after another.... multiple infections. Mostly my issues were allergies, and several years ago I was told I have nasal polyps. The salt water rinse seemed to have worked after the first week. that was a years ago, sometimes when i get a sinus infections, the Augmenten would not work, So the Doxycycline worked. Z-PAK works great for my too and you take that 5 days, but it keeps working for 5 days that.
Does you doctor know about the numbness, that could be VERY DANGEROUS, if you did mention it to the doc., then do so immediately
You might want to see your dentist. A bad tooth can cause sinus infections - and a "silver" filling can cause Mercury poisoning.
Wishing you well
