hello im katlyn. Im having extremly horrible pains and want to know how serious it is and how long it will last beffor i go to er. It usally happens if i get anything more than something like j egg sandwhich. Its it in the middle of my abdominal area you can feel kinda a lump on the left side in the v shape of outer rib cage in middle. It gets larger and shrinks back dwn. Constant hungry feeling with no appitite really gassy feeling with out alot of gas. Regular vowel movements pain goes back into my back in the center of spine and therd is a knot but that could be from sleeping weird tryn to get stomach pain to stop.
