I Might Have a Ruptured Appendix?

Hi, a couple days ago I came down with a cold. My tempurature barely reached 100f the whole time. A couple days before I felt symptoms, I started feeling a pain in my lower right abdomen. The pain was very mild and localized. I could pinpoint exactly where it was, and it had stayed there the entire time. Image I made here http://img376.Imageshack.Us/my.php?image=a bdomensurfdu4.jpg

history: I am currently taking tetracycine (500mg/daily), an antibiotic, and i'm a fifteen year old male. Ibuprofen 400mg for the pain helped.

I feel the pain when I am walking, but only very dull pain. I can sit down, lay down, and move my legs around while laying down with no pain. It was made worse after I exercising a little. However, when I went to the bathroom to urinate, it was competely gone. When I did urinate though, it took me a couple of times before I got it all out. Then it came back the next day.
Occationally, the pain will go away for a while.

Normally, I would write this off as nothing that would go away, however since i'm taking antibiotics it could mask symptoms.

Researching, I literally had a panic attack from bad anxiety. I just would like to put my mind at ease until I get insurance.
