Hi I really do empathize with you, im not sure if you have tried the testyourintolerance.com I found them after watching a tv programme, they were shown in. You can purchase various test kits from around £50 depending on how in depth you want to go, I had my test through within a couple of days and im not even surprised at the results, I knew that I feel ill if I have cows milk or egg white, I was intolerant to cows milk whey and egg white protein which I kind of guessed would come back, they give you a pretty in depth result, with advice from their dieticians
