I have had a cold for 12 days now and everything started getting better a few days ago, but today I have extreme sinus pressure, clogged ears, and I sound so loud to myself. On the plus size my chest congestion got better, but in return it seems to have went to my head. Dr. prescribed Levaquin tonight and sudaphed with pseudoephedrine. I ve tried netti pot and mega doses of vitamin c, tea and lemon and apple cider vinegar. Is there anything else I can do?
