Sudden Allergies Linked to RA Celiacs?

I will try to make this brief...

I am diagnosed with Rheumatoid Arthritis. Have been for 15 years.
Recently, I had a severe abdominal reaction, centered in my small intestine
Doctor put me on a liquid diet. Told me to stay away from gluten and dairy (they think it might be Celiacs, not confirmed yet). I was cleared to incorporate food back in 3 weeks ago, I was on the liquid diet for 3 weeks as well. Immediately I noticed reactions to other foods. Peanuts, chicken, red meat, sausage, bananas cause mild to mo4derate allergic reactions, and meat also makes my muscles very sore, and my bones. And everything remotely acidic gives me heartburn. Except for the heartburn, the rest seem like allergies. My lips tingle and burn, my eyes water, my throat itches, and I get really itchy. If I eat only rice, lentils, potato and select veggies, I am fine. Eggs make me gassy, but other than that are fine. And fish seems okay, too. Is it possible that I am suddenly allergic to everything? And should I avoid eggs and tree nuts? I havent tried any tree nuts. Thanks for any advice!

If you have any pollen allergies, you could be experiencing Oral Allergy Syndrome. The tingling lips and tongue are very common indicators. It occurs in about 30% of people with allergies, can pop up at any time. It occurs because your immune system identifies a protein in the food that is close enough to the protein in the pollen to cause a reaction. Sometimes cooking the food helps, but not always. It is possible for one's throat to close or to experience anaphylactic shock. You should see an allergist and, if it is OAS, carry an epinephrine pen with you.
Celiac disease caused all my allergies to worsen, before I was diagnosed, and causes OAS with many fruits and vegetables. You can find lists of cross-reaction foods for each of the major pollens and mold. It sometimes changes as seasonal pollens change.
Good luck to you!
