I'd be inclined to find a really good Paediatric Specialist (or someone who really listens and will make a real diagnosis) then try to find a good Naturopath or Homeopath to treat your little one. Natural medicines are highly effective in treating gastro-intestinal disorders, and will greatly reduce discomfort and pain.

You are doing a wonderful thing by posting on these forums - everyone is so supportive and willing to share their experiences. Hang in there, and all the best in finding a specialist who respects motherly intuition - they are out there somewhere!
