I am a 25 yr old who is on metoprolol tart 50mg BID because almost 2 yrs ago I had my tricuspid valve replaced (now pig valve). Long story short, recovering IV drug abuser who gave myself staph which led to endocarditis and after 2 months of IV antibiotics finally got cracked open and given a new valve. I take my bp meds everyday bid (not exactly the same time ALL the time, but mostly). Also every couple months I go a day or 2 w/o it because I dont have enough money for the RX (very rarely though, maybe 2x a yr). So every couple months or so I get this pain in my shoulder (side of heart) that also goes through to the same spot in the front of my chest. It hurts more when I take a deep breath in, sniffle, yawn etc. or even laying on that side (sometimes just laying down in general). I feel like it would be what angina feels like, (and believe it is) but I am trying to figure out why it happens. I was trying to remember if the few times it has happened, coincidently matched up with the few times I went a day or 2 with out meds. I assumed it was from that but now it happened again, but I have not missed any doses but..... I started my menstral cycle on tuesday and from me now not using any "drugs" I take the normal asprin, tylenol etc etc. This cycle my cramps were excrutiating and from my "tolerance to normal people pain meds" i took a nice amount. Started off with 2 aspirin, then tried a shower, threw up a bunch from the pain, then took 2 tylenol PMs. Fell asleep, woke up around midnight, 1am. Took 2 more PMs, fell back asleep. Finally woke up the next morning feeling ok, but about 1 hr later I slowly started getting that familiar shoulder/chest pain that I described before. Waited it out for the day/night then when Friday came and it wasnt getting better or worse I wanted to call my cardiologist but not in fridays. So i called my fam doctor but he is new to me (only seen him once). I told him about it and he said that he doesnt want me taking aspirin at ALL and there was nothing I can really do, it will fade away just stay away from aspirin. I wanted to ask more questions out of curiosity but figured id wait for my cardiologist. But im now wondering, I dont take otc pain meds (aspirin etc.) too often, maybe every couple months (coincidently) and wanted to know is it possible them times I thought maybe I missed a dose or 2 and got the pain, could it have been I took a bunch of aspirin like this time and got the pain. I dont miss more then 1 dose barely ever but the reason I thought it could have been that was because I couldnt think of any other reason. I get a couple really bad periods a year and that would fit with the timeline more then missing doses. See my doc didnt actually say it was from the aspirin, he just said, I dont want you taking aspirin at all anyway. And then when I asked how to make the pain go away he just pretty much said it will go on its own. I know this was soooooooo long and im sorry but I dont know this doctor that well and now its saturday night so either way I have to wait untill monday now. The pain is not unbearable or enough to scare me (probably because its happened before). I am just curious on the topuc I brought up. If anyone has any input it would be greatly appreciated, wether from a med professional or just a similar patient. Not looking for medical advice, just answers to why it happens. Thanks for bearing through my novel of a complaint! Jamie Lee
