Appendicitis?

[CEG123]

I am on vacation across the country. I woke up at 2:30 am with bad stomach pain (top middle), bloating, and gas. I went the the ER about 6 hours later and received indigestion meds. I felt much better outside of mild abdominal discomfort from gas still. Now the next day my lower right stomach is pretty tender, nowhere else, just lower right side. Should I be worried about appendicitis? Could it be tender from extreme gas and bloating?

Thoughts?
