I have tracheal malacia secondary to relapsing polychondritis. I also have pulmonary arterial hypertension. I had a crushed spine and suffer from spinal stenosis and have also developed fibromyalgia (if that is really a disease.) I currently have a bacterial bronchitis for which I am being treated with prednisone and augmentin. Can I take Delsym for this cough? I coughed so much I developed 2 hernias.
