Sorry I forgot to mention what they have done for his stomach. So far they have done a colonoscopy as well as many blood test and even a cat scan. All of them came back clean and they said there running out of idea's. He is also tried literally every thing to help him poop, but the problem is he is scared to take them because it hurts so much worse when he takes it and just falls asleep within an hour or two and then he has to do it again. The miralax really works but it puts him in so much pain he can't cope with it.

Thanks for all the support and replies!
