I was just dignosed in April and I have a sister who suffers from many of the same symptoms that I had. She went and had the blood test and it came back negative, so her doctor said she didn't have to eat gluten free. I explained to her that she may not have celiac, but she may still be gluten intolerant. She refuses to even try eating gluten free to see if she would feel better, but I bet she is like you. But her doctor, being a GP probably doesn't know enough himself to have recommended she try eating gluten free, just in case she had gluten intolerance. So I agree with your concern. It may be an education issue for doctors to understand that negative celiac test doesn't necessarily mean you don't have a gluten problem.
