Hi, our son has had Tourette’s for several years. We have tried magnesium but it’s no longer working as well as it used to. I’ve seen many posts about aspartame/gluten/etc causing tics. Aside from elimination diets, are there any tests we can request from our doctor to test for sensitivities? If so, what sort of test and who would perform it (MD, naturopath, etc).
