Hi, I think I'm suffering from Precordial catch syndrome (PCS) - this is a self diagnosis that I've come to based on the following symptoms that I've observed - 1. Isolated events of chest pain without any specific pattern or any triggering agent. 2. When pain occurs, it causes inability to take deep breaths 3. It goes away in under 1-5 min But based on my online research PCS is accompanied by a bubble pop kind sensation in the end which leads to relief, but in my case relief just comes by - rest all the symptoms seem to be consistent. Is there anything I should get tested or checked to be sure - what else can I do in this case? Or to how else I can be sure of the diagnosis and rule out the possibility of any other problems.
