I have an having extreme shortness of breath. It feels as if there is a band around my chest. I also start coughing up small gobs of blood. I break out in a rash and have horrible itching. My face and around all my joints is swollen like the moon. I am on this for a flare up of lupus. I have major imflammation in my blood. It caused fluid to build up around my left lung. When I take the meds, about a half an hour later is when I start feeling the band tightening around my chest. Could this be the prednisone?
