Sudden upper back pain, chest tightness? Never felt this before!?

I'm a 29 y.o. female. A few weeks ago I developed these symptoms very suddenly, while lying on my left side in bed:

* Heaviness in chest
* Sharp pain in stomach, right below sternum
* Upper back tightness, pain
* Shortness of breath.

Symptoms went away when upper back was massaged deeply. Massaging stopped, symptoms came back. Massaging restarted, symptoms went away. All in all, I was knocked down by this for about 20-30 minutes. When it went away, I felt like nothing had happened at all.

That same day I had started antibiotics for strep throat. Had taken first dose 10-15 minutes before symptoms started. Completed 10-day regiment of antibiotics, symptoms haven't come back.

I suffer from PSVT, but never had anything like this happen before.

Other medication being taken at the moment: tylenol with codeine for the throat pain, Yaz contraceptive.

At first I thought I didn't have enough water and the pills were stuck in the trachea, causing all that. Any ideas?

I would definately talk to your doctor about the symptoms that you had. What did you eat before you took your meds? I had similar symptoms a few years ago and it turns out I had gallstones.

best get yourself checked asap. could have been a heart attack. you want to rest assured, so get it checked out.

See doctor might be heart problem,allergic to antibiotic?

When I was a sohpmore in high school, I started hurting exactly the same way you are. I'm not sure if we have the exact same thing, but my doctors thought it might be a new type of juvienille arthisis. If you need more info, you can contact me. Damaster2262@yahoo.com. I hope you feel better.

Don't take any chances. Get to the Doctors asap.
