Hello,
It can be due to hives. Hives (medically known as urticaria) are red, itchy, raised areas of skin that appear in varying shapes and sizes. They have a tendency to change size rapidly and to move around, disappearing in one place and reappearing in other places, often in a matter of hours.

Many cases of hives are "idiopathic," meaning no cause is known. Others may be triggered by viral infections or medications. Treatment is by oral antihistamines. You can also apply 1%hydrocortisone cream on the effected area. Try taking Vitamin C along with this treatment. Vitamin C is a general anti-allergy supplement. It helps stabilize mast cells so they are less likely to release histamine.

Please see your dermatologist if the condition does not improve. I hope it helps. Take care and regards.
