It’s understandable to feel frustrated, especially when you’re managing celiac well but still experiencing new, unexplained symptoms. Many people with celiac notice sensations around the neck and jaw area, even without visible swelling. Sometimes, lymph node sensitivity or a tight feeling in the throat can linger as part of the body’s inflammatory response, even if your thyroid and other tests come back normal. It sounds like you’ve been thorough with testing and have seen multiple specialists, which is great. A few things might be worth considering: for some people with celiac, there can be lingering sensitivities to trace gluten, cross-reactive foods, or even certain environmental factors that can cause persistent inflammation. Since you’ve tried antihistamines and a humidifier, you might want to discuss options like different allergy medications or seeing an ENT specialist if you haven’t already. Some find that supplements (like anti-inflammatory options or probiotics) help support overall inflammation reduction, though you should always check with your doctor first. It’s frustrating when you feel the symptoms without an obvious cause, but trust your instincts—hopefully, with persistence, you’ll find answers and some relief soon.

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.
