Martha, I also get urticaria from temperature fluctuations. Usually, mine are from a rise in my body temperature, but I have had incidents in cold temperatures. I tested positive for Alpha Gal, with strong allergic reactions to beef, pork, and dairy. I also have numerous food allergies, aside from the ones I already mentioned. There is a definite connection between Alpha-Gal and temperature fluctuations in some people. I feel my uticaria is minimized on a diet free from dairy, but I still have allergic reactions that I can’t explain. Mine started over a year ago, and it’s been life changing, because everything is a potential allergen. For what it’s worth, you are not alone with this.
Every board-certified allergist first completes at least three years of specialty training in either internal medicine or pediatrics, and then completes an additional training program of two or more years studying the diagnosis and treatment of allergic and related diseases. Certification by the American Board of Allergy and Immunology requires not only approved training, but also successful completion of a challenging written examination. Every board-certified allergist thus has credentials in at least two specialties and is qualified to care for both children and adults.
