Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of itching skin along with formation of bumps over the surface of skin seems to be
Contact DERMATITIS and can occur due to a number of reasons like allergy to washing powder, soaps and skin cosmetics, leather used in belts, Medication, poison ivy etc
You should consult an Allergist and get evaluated and a thorough clinical evaluation and laboratory investigations like
Patch test, RAST test can help in ruling out the allergen and an
Immunotherapy can be started to reduce the severity of allergy symptoms..
He can also advise you to take Oral anti allergics like Levocetrizine or
Fexofenadine ( Allegra) to relieve the itching..
Continue using
cortisone ointment and also can do cold compresses over the bumps..
Hope this information helps..
Thanks and regards.
