About four weeks ago, was getting increasingly winded and started to have episodes where I couldn't get a breath. My primary thought it was reactive airway due to a sinus infection and gave me inhalers. A week later, my symptoms were getting worse so a ct of the chest was ordered. It showed a large pericardial effusion. I was seen as an urgent patient by a cardiologist two hours later, had an echo and admitted to the hospital where I had one liter of blood drained the next day. I was sent home the following day. Three days later, symptoms returned and a new echo showed fluid returning but this time the aortic chamber was collapsing. This time a cardiac thoractic surgeon drained me, did a window and biopsy. The biopsy showed idiopathic pericarditis. Yesterday, when I changed the bandage on the hole from the site the drain had been, the discharge was turning from yellow to GREEN. The doctor did a white count which was elevated, cultured me and put me on two antibiotics which I started yesterday and am taking until the results of the culture come back. Last night, 6 days post op, I got sudden sharp pains under the left breast extending into my shoulder and neck. The only thing that helped the pain was sitting up. I called the cardiologist on call this morning and he felt that I was experiencing pain from pericarditis. He phoned in colchicine. I took my first dose this morning and am also taking ibupoferine. I am 57 an until now NEVER had any cardiac problems at all. Talk about coming out of the clear blue!!!!! How long does it usually take for the colchicine to really kick in. Could the possible surgical infection have caused the sudden pericarditis pain?
