At least, that's what it feels like. I started Prilosec for 4 days on doctors orders when I was feeling sick. It turned out at the time my depression meds were off, which was causing flu like symptoms. Since fixing the meds I've felt better, but the Prilosec caused new issues. I've never heart problems in my life, but I woke up on day 4 of the treatment with a racing heartbeat, like I was having a heart attack. I went to the ER, and they gave me a Halter monitor to wear for 48 hours. I left the ER with the diagnosis of "tachycardia" which my folks told me is basically a fast heartbeat.

While I was certainly scared that this happened, (since it never happened before) I kind of shrugged it off and hoped I could get to sleep. I slept fine the next night, but I woke up with a strange feeling in my chest. My chest felt pressured, then felt light, it was very strange. Even as I type this, I am up because it's bothering me so much I can't sleep. My heart rate does all these weird things like dipping and jumping and it feels like sometimes it stops and starts again, just really crazy feelings I've never had before.

I stopped the Prilosec on the 5th day after a doctor on the doctors exchange told me stopping was probably best. But ever since, I've had strange chest pains, pressuring feelings, ringing ears, every now and then terrible left arm pain, dizziness, worse than before heart burn, and it's just all really scaring me.

I've had GERD for about 5 years, and it's been untreated for the past 3. I was on Nexium 3 years ago, and it seemed to work okay, and I didn't have this kind of reaction, but it still wasn't worth the money so I stopped. I haven't changed my diet, and I am overweight by some deal. But I am truly worried something major is wrong, and my folks can't seem to convince me otherwise. Having OCD, depression and anxiety doesn't help the mix, either.

So right now I'm just wondering, could it be the Prilosec, the missed doses of my anti anxiety medications, (Luvox and Seroqeul) or something else?

Any help would be greatly appreciated. I am truly scared right now and could use some help or reassurance. Thanks.
