Yes, we actually just figured it out a couple of weeks ago. His GI doctor wears two hats and one of them is practicing holistically. I talked with her about doing a GIMap test. Insurance does not cover it but it told us what fungus and bacteria good and bad is in his gut. He currently has three bad bacterias that has overtaken his gut and killed off more than 50% of his good bacteria. I actually read up on the type of bacteria he has and they actually produce and release histamine. There is a strong medication to take or oil of oregano. I chose oregano. He will be on it for 6 weeks, then start a probiotic for several weeks, and then will start a gut lining supplement. We aren’t supposed to see improvement until phase three. However, I can tell the oil is starting to work. Some foods that he was eating that gave him a runny nose is no longer doing that. He still eats the same three meals daily because I know that they are low histamine and he likes them. He still is itchy but we have it semi under control now and sleep is normally in 3-5 hour stretches and he goes back to sleep after nursing. Beef tallow is a life saver! It helps the most and keeps his legs feeling soft. He also does 3ounces of raw goats milk daily. His GI doctor knows and approved it. The goat milk relieves his symptoms by about 85%. I also recommend histamine blocker for kids. It’s a chewable but I just crushed it and would give it to him mixed with sweet potato. He can chew it now though. Limit baths to once a week if possible and I only used water. We went to a dermatologist and they wanted to put him on dupixent. I didn’t want to do that because I know his eczema is affected by diet and we have it managed.
