Pericarditis

Has anyone had pericarditis before? I was just in the hospital for chest pains (been having them for months) they just kept getting worse and I started getting back and arm pain. They did all the tests and said it’s pericarditis. Gave me meds to take for a month. They asked if I had a infection or covid before and I didn’t that I know of. I do remember 2 months ago I randomly started getting body aches really bad in my neck shoulders and jaw. I thought it was my wisdom teeth. But now I’m getting them again I just feel weak and tired. Pain in my upper back. My muscles hurt. Is this what comes with pericarditis? My doctor didn’t really go into detail because I already have an appointment with him in 2 weeks.
