    Perplexing "asthma" problem - what is this???
    circusacrobat posted:
    I'm having extreme bronchial spasms that come and go - feels like severe hypoxia (can't catch my breath, panicking, hard to exhale), but my O2 blood saturation is 96-99%, my peak flows are off the chart (>850), and no wheezing. Flovent provides relief, but it only lasts for about 2 hours. Been to the ER and UrgentCare in the past week. My doctors are stumped. EKG, chest x-ray, D-dimer, NO test -- will have a CAT scan this coming Friday.

    This episode started 3 weeks ago with a chest cold. Before, I had very mild asthma for 10 years -- Ventolin puff maybe once a month. The chest cold turned into a sinus infection. Was prescribed azithromycin and prednisone tablets (40mg). Then 5 days later, my breathing worsened a lot. Any idea what's happening to me?
