Ok Over 24 Hrs Ago I Had A Upper Endoscopy

Ok over 24 hrs ago I had a upper endoscopy procedure. Last night I had a bowel movement, with no blood. I've not been throwing up or nausea! He took two biopsies, inside my esgaous. And performed a esagous stretch. Reason for procedure was trouble swallowing. My concern now is I've got massive bloating unable to pass gas, with a severe burning sensation on the right side of adomen. Is this a emergency? I haven't went to a e.r because no insurance! I've taken Maalox but it's not helped none! Thanks for any feedback.
