Methylprednisolone
"I was prescribed this yesterday at urgent care for a very slow growing allergic reaction since it was starting to affect my throat. I felt instantly better during the first day and dealt with the common side effects with appetite change and sweating which I was okay with.

When I woke up though on the second day though, my chest had unusual palpitations and it's making me lethargic and my mood is pretty numbed.

My doctor warned me of all the side effects, but the palpitations aren't a part of it so I'm worried. If it doesn't get better before I take my second pill for the second day I'm going back.

It sucks because this medication was really working. I'd rather have prednisone instead, that worked before and less effects."
