For a couple of weeks i have been experiencing backaches, cramps, and it takes a very long time for me to fall asleep. I am 17. A couple of days ago, I was asleep then awaken by a pain in my stomach, then i went back to sleep. The next day (or maybe he same day don't remember) I rushed to the restroom, and I couldn't go at first then i threw up. After that i had diarrhea. During all of the weeks of backaches and such, my diarrhea came and went but, it wasn't until the first time i threw up that all the pains grew worse. After every meal my stomach hurts. Yesterday i ate dairy queen and right after my stomach cramped. I went home. Couldn't go, so i took a nap to ease the cramps, then i woke up & ate arbys. I still couldn't go so my sister gave me some Dulcolax(overnight relief) because it was getting late. First i took 2, and nothing happened so i took one more. its 1-3 tablets daily. IT DID NOT HELP. I was just constipated until this morning along with more cramps. I finally used the bathroom, but this time i threw up again, (orange, i'm guessing stomach acid) and had diarrhea, It was horrible. Now i have to keep going back to the bathroom cause i'm never finished. My stomach still hurts i'm just drinking water. I ate some grapes & thats it this morning. Advice please?
