Just because you do not "believe" in any testing outside of the kind you provide, doesn't mean those that do are quacks or those that provide it are scam artists. And yes, food intolerances do cause IG/digestive issues...like reflux as well as congestion/respiratory /sinus issues. Had I not been trying so hard to get him to tell me who the "quack" in town was that does these "scram" tests that I WILL have done, I would have really given him a piece of my mind. He didn't want to get sued for slander so he wouldn't tell me who it was. Had I not personally gone through absolute hell for a year and half with "modern medicine" not being able to diagnosis my health problems, I probably wouldn't feel as strongly as I do about this. I'm so grateful for those experiences and the education it provided, but mostly I'm so appreciative for the confidence that journey instilled. I don't know for sure if my boys have any issues but projectile vomit after every meal is not normal and I intend to find out the cause, not just treat the symptoms. If that makes me a quack, then I'll wear my duck suit proudly!
