I had a dizzy spell earlier tonight. It started with mostly loss of hearing in my left ear. It was followed by a near fainting. It also caused some nausea. It left as quickly as it began. All-in-all, maybe 5 minutes. I just started on prednisone to treat an asthma, possible infection, likely viral in nature. I have a productive cough (green globs), but coughing comes in spells, not constant. I also take Mucinex DM, Singulare, and Chlorphenamerate (not sure about spelling of that one). I have a nebulizer and I also take Benadryl at night.
