About 3 weeks ago, I went river rafting and it was tough on my abdominal muscles, they were extremely sore after, especially on the right side. I had felt a cough coming on the day before rafting but went anyway, and the day after was hacking up a lung. I've had the cough for almost 3 weeks now then about a week and a half ago, I started experiencing a sharp pain in the lower right side of my abdomen every time I cough, laugh, get up, sit up... well anytime I use the muscles. The pain is very dull to absent when I'm sitting or laying down.
Now, I'm really freaking out b/c I have had a few people tell me it could be appendicitis, and that I should go to a doctor immediately. Do you think this is a pulled/strained/torn abdominal muscle? Or should I go get my appendix checked out? I'm supposed to leave on vacation tomorrow and don't want any 'EXPLODING' surprises. HELP!
