What medical conditions could cause recurrent itchy skin rashes and subcutaneous bumps that persist despite taking cetirizine, accompanied by increased facial heat, a burning sensation, and paresthesia (pins-and-needles) in the limbs?
When itchy rashes and bumps are accompanied by facial burning and pins-and-needles, it suggests something more than a simple allergic reaction. Sometimes, conditions like chronic urticaria, thyroid imbalances, or autoimmune-related inflammation can affect both the skin and the nerves, causing these varied sensations. Please don't worry, but I do highly recommend consulting a primary doctor or a dermatologist. They can run some simple blood tests to find the exact cause and help you find a treatment plan that finally brings you comfort.
