Hi WatchmedreamI've read this thread and your other one.You said your doctor won't do any other testing other than ultrasound and Xray...is there a reason for only those two tests being approved? What kind of doctor are you seeing...a family doctor or a GI specialist? That can make one heck of a big difference in your diagnosis,care and treatment. If you're only seeing your family doctor, ask for (have your parents request) a referral to a specialist. There is no reason you should have to be enduring this without more extensive testing being done to find the cause.And as many people here will tell you....there are many, many diagnotic tests that can be run.In the meantime, as hard as it may seem, try to lower your irritation/anger level. I know how it feels, but its really only being counterproductive at this point. If your parents aren't taking you as seriously as they should, perhaps you can talk to another adult that you trust..whether at school, another relative, etc. Someone will listen..but you have to approach it calmly and not let them think you're over-reacting. Even us old people aren't taken too seriously at times...believe me. It doesn't just happen to 13 year olds. I've had the pat on the back by a doctor and told the line "You'll have to learn to live with it Sweetie". (That guy was lucky he got his hand back with all 5 digits attached!)Don't give up....and don't get angry. Get determined that you WILL get someone to listen to you seriously. And as someone mentioned in the other thread....the right KIND of fiber can help, but three days isn't long enough to determine if it will help you. Fiber has never helped me, but everyone is different. Have you ever resorted to laxatives of any kind by the way? Some people that have overused have a very difficult time feeling the urge to go on their own.
