About 3 days ago 3 small areas of red, extremely itchy (and slightly painful) red bumps appeared--2 on my back and one on my chest . The areas are small clusters of red bumps, no sign of puss, scabs, etc. Extremely itchy. Bumps in clusters on my back are larger and not painful, while the area on my chest has bumps that are MUCH smaller and there is a spot close to that cluster that is painful. I ve had no interaction with poison ivy or oak, no change in diet , am on thyroid medication . There HAS been a change in laundry detergent--same brand I ve used for years, but a different scent. There is also a new cat in my household (there was already a cat present, so cat allergy seems doubtful). Any help is greatly appreciated.
Hello, It is unlikely cat or animal dander or allergy to the new detergent as this happens randomly. Urticaria is the diagnosis and underlying thyroid dysfunction plays a role in aggravating the urticaria, although the exact mechanism remains uncertain. Thyroid autoimmune disease may reflect that the urticaria you are having is autoimmune for which a long period of antihistamines (avoid sedative ones) are required to control the urticaria.Also, you must get a TSH, fT3, fT4 checked if there has been a change in the thyroid medication dose (presuming you are on Elton) and also otherwise as underactive or overactive thyroid can aggravate the urticaria. Thanks.
