About 9 months ago I did severe physical efforts for several days, and about a week later I developed costochondritis on both sides of the lower chest, and also PVCs and PACs. All cardilogical tests, including cardiac cath, were negative, and I was prescribed Flecainide by a cardiologist, neither him or internists I saw gave any importance to the simultaneous appearance of those different symptoms. Is there any treatment for this syndrome?
