For 4 weeks, I have had persistent low-grade fever (up to 2° higher than my normal) and cough with upper chest congestion (wheezing on exhale). Have taken Z-pack (5 days), then Levaquin (7days), then Levaquin with Omniceph (7 days) with Prednisone (6 days). Blood work came back normal (and specifically no Valley fever). Did test positive for pneumonia. But after 4 weeks and all that medicine, symptoms persist. Inhalers and ventolin treatment don't seem to make a difference. Yesterday, I started taking Singulair and after first dose, it did actually seem to help - congestion seems less and I simply feel better. If this is asthma (never been Dx'd before with it) or allergies, shouldn't inhalers and prednisone have also made me feel better?
