Hi, I'm 15, and throughout my childhood and now, including today, I've been experiencing abdominal cramps, pain, constipation and diarrhoea. Its always disappearing and appearing, and when the cramps hurt they really really hurt. There were only 3, thank god, major pain where I was sent to the hospital. I've always suffered from chronic constipation, and they told me to eat more fruit and drink more fluids. I exercise regularly but these pains are always mysterious, since I don't know whats the cause. I'll try and list the symptons:-Chornic conspation-Mostly hard feces-Cold sweats whenever the pain starts-Very weak and I don't want to eat or drink anything-Lots of gas in stomachWhen we call the ambulance whenever the pain gets really bad, it always disappear right before they come to our house. I don't know why, and the paramedics always think I have appendicitis. And then I'm all fine when I reach the hospital. And when the pain strikes, I wish I was dead so I don't have to suffer it. I remember once when I hid in the toilet, and there was a huge, maybe even record breaking size of the feces stuck in me. I was in pain and trying to wait for it to come up. In the end I had to use the toilet rolls's cylinder to try and pry it out. I was shaking all over and sweating when I finished. The pain is also weird, because sometimes its here, and sometimes its there, and even a small amount of noise will annoy me a alot. And then I would wish it was hot, even though it was already warm in the room, and I would lie in bed in spasms, and the pain seem to radiate to my groin, like if I was trying to pee and I don't have to pee. Now, whenever I get the pain, I would get into a fetal position on the floor and just lay there, trying to stay quiet and just hope the pain would go away. There are also times when I would get gas in my stomach which wouldn't come out and I would also be in severe pain. Oh and I'm also severely underweight, and I still don't know why.Anyway these pains in my stomach and abdomen is occuring randomly, and I don't know why. What is wrong with me? Do I have IBS?
