Thank you.

Trying to do research for my wife. Five days in Hoag Hospital with Pericarditis. Idiopathic. Treated with Prednisone. Long story short, complicated situation. Trying to get a handle on the why? (Doctors et al were great. Just doing our own research.) They ruled out all the expected, like autoimmune, bacterial infection, arthritis, etc..) Any thoughts? Thank you, Mike
