[|AI|]  Hello, Thank you for posting on Chat Doctor. From your description, It's difficult to put forward a definitive diagnosis. I would thus suggest you to consult a dermatologist for proper management, or alternatively you can post pictures to me via direct query so I can help you in a better way. Given the history of Hypothyroidism and sudden development of itchy rash I would like to put provisional diagnosis of Urticaria or hives.It's an allergic manifestation of skin, where an allergen leads to release of certain substances from your blood, leading to itchy skin rash and swelling over soft tissues. Its proper management requires thorough history, clinical and laboratory work-up. You may have to go for specific tests like patch test, food prick test, IGE antibody levels etc. As for treatment part, best would be the avoidance of allergen as far as possible. Try to eliminate possible triggering foods from diet. I would also advise you various antihistamines for long duration(at least 3 months) with or without oral corticosteroids. For non-responding cases there are many other Chat Doctor.  Hope this will take care of your condition. Kindly spare some time to rate my answer and
