What to check out next. I have had chest pains, more of an ache, going on since an emotional event in February. The pains aren t necessarily induced by stress, as they happen more at night and position doesn t matter (sitting or laying down). They have gone into my back and down my left arm to twinge between my index and middle fingers as well as in my wrist. I have taken my inhalers before thinking it was related to asthma, no effect. I have taken an antibiotic for the full 10 days as doctors thought it was bronchitis, no effect. My BPs were up (160-158/102 -98) so I have been put on atenolol 50 mg to help. I have been battling high cholesterol for 12 years and recently went on a statin (zocor 20mg) for that. I am termed pre-diabetic with my lab results and my liver enzymes are noted to be high but said to be ok ? I have had a good EKG, good stress test (7 mets reached without issue) and clear cardiac cath but since the cath 2 weeks ago, I still get the chest pains but they are quick and almost like a zap. It can feel like my diaphragm is getting punched up into my heart/chest and goes away just as fast. Over the weekend I have had 2 sets of 3 zaps right in a row, like a pulse. And Thursday before last I had 12 such zaps to the center/left of center area of my chest where the first four zaps felt the strongest but the 4th zap being the strongest of the first four, then each faded but I counted 12 in all. (would that be a cluster?) I ve tried Prilosec OTC also to see if it was related to heartburn but that also had no effect. Could this be Printzmetal s angina?
