question: Hello, I am a 19 year old male and have moderate to sever pulsating pain in my lower to upper abdomen that radiates to lower back and hips as well as pencil like stool. I was recently constipated (lasting 6 days) and told to drink magnesium citrate a day ago. This made me produce diarrhea for about a day. That was yesterday and today these symptoms have occurred with a constant abdominal pain changing in severity throughout the day.
