Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain the symptoms of itching followed by appearance of bumps seems to be due to
Contact Dermatitis secondary to
allergic reaction to things like any skin cosmetic or detergent..
It can also be due to allergic reaction to poison ivy, leather, latex, certain medication etc..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigations like Prick test,
Patch test,RAST test, Food challenge test to rule out the exact cause of the symptoms and treatment you accordingly..
As of now you can take anti allergics like
Benadryl or Levocetrizine to relieve itching..
You can apply Steroid ointment over the rashes..
Do cool compresses..
Apply Calamine lotion to soothe the skin..
In case of recurring episodes an
Immunotherapy can be instilled to reduce the severity of allergic reactions..
Hope this information helps..
Thanks and regards.
