<p>Lactose intolerance can come on suddenly (it did for me) with gas, bloating, and a pain that felt like I had someone cutting me with scissors from the inside on the right side near the appendix. The pain finally went away when I removed all - and I mean even that drop of milk or bit of butter or bread made with whey or anything else that contains whey or is prepared on equipment used to prepare food with milk - all - traces of milk from the diet. I can turn that pain on and off based on milk food. Lactaid (the pill - and the brand - other brands don’t work for me but do for some other folks I know who are lactose intolerant) helps some but not totally.</p>
<p>FWIW - my symptoms are not as extreme as it sounds like your sons are, but it’s something to consider.</p>
<p>Also, DS had a hernia which caused pretty intense pain. They had him drink the gunky stuff and have a scan to diagnose, and surgery soon after. </p>
<p>Also, lactose intolerance can be a side effect of celiac disease - if your intestinal lining is injured, then it is hard for your body to make the lactase (the enzyme produced in the lining of the intestines) that helps digest the lactose (milk sugar that causes the problems). I notice that if I toast bread very completely, really cook the flour so none of it is gummy, my lactose sensitive belly is happier with bread stuffs. For my body the two, lactose and gluten, are def. connected digestively.</p>
<p>And, Crohn’s can also have lactose intolerance as part of the problem. My neighbor has Crohn’s, and when I described my lactose pain to him, he said that is exactly where his Crohn’s pain is, and he went to his doc and asked to be tested for lactose intolerance, and was found to have 0 ability to digest milk. It would have been <strong><em>nice</em></strong> had the doc’s figured this out for him - but they did not. His symptoms decreased after he removed milk from his diet. He did not pursue Celiac - this was a couple decades ago now. At that time my doc actually laughed at me when I said I was lactose intolerant - I figured it out on the brand new internet chat groups, when some folks responded to a post to warn me about vitamin pills, which can be bound with lactose. So watch his pills, too!</p>
<p>Good luck!</p>
<p>Also, celiac is not as difficult to live with these days as it was a mere 10 years ago. You will find a local supermarket with a section filled with appropriate food choices. There are many brands out there now for both lactose and gluten intolerant folks. It’s a challenge, but very handleable once you get the hang of it.</p>
<p>The local elementary school could probably be a good source for you - there a lot of kids now with various food intolerances, and the school nurses have some good info, usually because they hav been educated by parents. I knew one celiac kid who couldn’t touch play doh - there are odd sources of gluten out there, so if your son is found to be celiac, there are some things like that to watch out for. There are also groups around - google for it - lots of info on how to eat well on the web and so forth. </p>
<p>I ran in to some gluten intolerant women shopping a few years ago and they were the ones who told me about the lactose/gluten connection which I then researched on the web. They said it is so much easier these days to find foods. Even some restaurants will be sensitive to your food needs, since there are so many ppl out there with various food related issues.</p>
<p>Good luck!</p>
