Major tummy ache? Help?

So lately I've been getting bad indigestion, today when I got home from work I was feeling so full I ate chicken tenders, and a snickers bar and a taquito before I got home , I've been home for 2 almost 3 hours I still feel a little full, I've been popping non stop and it feels like I have to burp but I can't. Everytime I try to lay down and go to sleep my stomach starts hurting really bad. Now my tummy hurts I think I pooped everything outta me ! I had sparkling water but no luck. Help?! Please lol!!
