i don't know if this will help but , when my son was 7 he had the exact same problem. he had every test there was to give! of course medicine is not an exact science, and time has changed since... please be aware ,that males do have over 700 known intestinal and stomach bacteria disorder possibilities and more allergetic disfunctioal possiblities! and probly twice as many not known! the process of elimination is tuff!u may be in for a long ride and it is awful when your son wakes up from a sound sleep in excruciating pain and nothing seems to help much...please know, my son is now 14 and he did within about two- three months get better...never found the problem! good luck!
