Common causes of recurrent rashes include hives or urticaria. Theses rashes usually appear and lasts for minutes to hours before they resolves.
Urticaria is generally classified as acute or chronic urticaria based on the duration of the rash. If it is less than 6 weeks duration, it is acute urticaria and if is recurrent beyond 6 weeks, it is considered chronic urticaria.
There are many potential triggers of acute urticaria. These can include food, viral infections, and physical factors like temperature changes and pressure.
Urticaria usually responds well to oral antihistamine treatment.
If your rashes have been persistent or recurrent, it may be advisable for you to see your dermatologist or doctor to confirm the diagnosis and advise you further on the treatment and management.
