Pulmonary embulism symptoms and conditions

I began prednisone May 20th for hives from a reaction to an antibiotic. After taking it for a few days I started having ringing in the ears, shortness of breath, tightness in the chest and sweating, dry mouth, puffy face and just a strange feeling like my blood pressure is up. I took it for 7 days out of the nine because the nurse told me to stop it after I called in about how I have been feeling. Today is the first day of not taking it but I see hardly no improvements. My husband tells me to drink a lot to flush this medication out of my system. Today I am experiencing some chest discomfort with slight aching. I feel the same as all of you. I wished I knew of this drug beforehand, and I hope to never see this drug again. I just hope it didn't cause much damage. I will be praying for all of you. No one knows any more what can happen after taking such medication. If you are on this call your Dr. to be taken off. This is not good, I have no idea why this is still on the market. Hope you all recover from your symptoms after taking this drug!
