It sounds like you’re really going through it—accidental gluten exposure can definitely take a toll, and when it happens twice close together, it can feel like it drags on even longer. Many people find that each glutening is a bit unpredictable in terms of recovery, and it could take a little extra time if your body hasn’t fully cleared out the first exposure before the second one hit. Staying hydrated, avoiding other potential irritants (like alcohol and spicy foods), and resting can help ease the symptoms as your gut heals. Hopefully, things start to settle soon! In the meantime, it could be helpful to communicate with friends about specific brands to look out for, even when it’s hard to ask in the moment. Hang in there—hope you’re feeling much better soon!

@Therockfrog, it sounds like you’ve been through so much, and managing these symptoms must be incredibly challenging. Tingling in your feet and scalp, especially after eating specific foods, can sometimes be related to histamine intolerance or even a sensitivity to certain food proteins, as you’ve suggested. Since you’ve already noticed patterns with gluten, nuts, and dairy, it might be worth looking into a histamine intolerance or mast cell activation syndrome (MCAS), where the body has an exaggerated response to histamine and other triggers, which can cause itching, tingling, and even high cortisol levels. This would explain why your symptoms change with seasonal pollen too. If you’re considering eating some of these trigger foods before seeing the allergist, it could help with identifying specific IgE reactions. However, since this can worsen symptoms, you might consider working with your doctor to approach this slowly, maybe introducing one trigger at a time. It’s great you’ve tracked your symptoms so closely—that detailed information will help the allergist a lot. In the meantime, perhaps continue with antihistamines, as sometimes trying different types (H1 and H2 blockers, for example) under guidance can make a difference. Hang in there! It sounds like you’re very close to finding the root of these reactions.

Exciting news for sure, especially the fact that "existing drugs could be used to interrupt the inflammation process and help treat patients." Having to develop new drugs to target this genetic pathway would take many years, so finding existing drugs that do so could greatly speed up treatments.

Since your daughter has celiac disease some studies show that up to 44% of first degree relatives also have it, and it sounds like it is very likely that your house may be going gluten-free soon, mostly anyway, due to your daughter's recent diagnosis. If you are in the UK (since you spell it "coeliac"), you may get subsidies and other health system benefits if your son is also formally diagnosed, however, the situation you describe would be very difficult to deal with, so I would have him go gluten-free ASAP to see if it helps with his symptoms (but be sure to alert his doctor that you are doing this, and why you are doing it). If his test is positive and his symptoms improve on a gluten-free diet, try to get the doctor to diagnose him without a biopsy, otherwise he would need to eat lots of gluten each day for 2 weeks before doing a biopsy. I hope things improve for him, and let us know how the test results turn out.
