I have had abdominal pain with back pain for almost 12 hours now. It is pretty intense and doesn't seem to be easing in any way no matter what I do. Should I go in to the hospital? I am thinking it maybe gull stones based off my symptoms and webmd website.

Instead of assuming yourself that you have a gull stones. I recommend you to go the hospital & consult the doctor regarding your problem & on his/her behalf take proper medication for your abdominal pain. She/he will give you the right suggestions to you regarding your issue.

Gallstones, not gull stones. Yes, you need to be seen by a doctor if the pain is still significant after 12 solid hours.
