Hello,
Thank you for asking at HCM.
I went through your history and would like to make suggestions for you as follows:
1. From your symptoms, I would think of
urticaria with
angioedema.
2. Common causes are allergies, infections, drugs (mainly analgesics & antibiotics)sometimes autoimmune and sometimes cause may not be found. Also some physical factors like exercise, sunlight exposure, cold/heat exposure, water exposure, pressure etc can also trigger these symptoms.
3. If the trigger is known, avoidance of the trigger is the best option.
4. For symptom relief, an antihistamine like
cetirizine or
hydroxyzine can be used. It may take 3-7 days for complete resolution of symptoms.
5. The autoimmune disorder you read may be "autoimmune urticaria".
Hope above suggestions and information will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish you the best of the health.
Thank you & Regards.
