Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain persisting red itchy bumps over the body can bedue to causes like
allergic reaction to any unknown allergen and can be any food or medication, while can also be due to allergic reaction to any detergent, skin cosmetic, leather, latex, poison ivy etc..
Other causes can be Scabies and hair
follicle infection or
Folliculitis..
But as the antibiotics,
steroids and scabies treatment did not relieve, it seems to be most probably be due to allergic reaction..
I would suggest you to consult an Allergist and get evaluated and a thorough clinical evaluation and investigation like blood tests can help in diagnosis and treatment can be done accordingly..
You can be advised to take anti allergics like Allegra or Levocetrizine and steroids..
Application of steroid ointment and cool compresses can also be done..
Apply
Calamine lotion to soothe the skin..
You can also be advised injectable steroids to relieve itching soon..
Hope this information helps..
Thanks and regards.
