I have Precordial Catch Syndrome and it is apparently not supposed to happen/wake you up during sleep. This has happened a few times for me and I am currently over 12 hours (including sleeping) when the pain has not been relieved. Should I be worried?
Well, it is mighty hard to diagnose precordial catch and not have it be possibly something else. Most of the other causes are similarly 1) non-serious and 2) treated with NSAIDS about the same. There can be irritation of the rib joints (costochondritis), other aches and pains, minor irritation around the lung (devil's catch). There can also be pneumonia, a tumor, angina, depression, anxiety, and probably many other disorders that can cause similar problems. Simple exam with simple tests can help eliminate some of the problems.
