Hi, I am hoping someone can help me. I was diagnosed mth ago with small effusion pericarditis, and was treating it with anti-inflams. not much pain relief, now the pain is getting worse, almost constant pressure, trouble swallowing, talking alot makes it hard to breath and painful..... and the sternum pain now goes right thru to the back between the shoulder blades. I am waiting for another cardiologist referral, and am wondering if i should be going to the Emerg. dept or not... dr. put me on oxycodene for pain, but didnt want to use much of that nasty stuff.... any ideas?
