It will comes whole body any place and looks bubbles and it that place itching and burning feeling and she cannot able to tolerate in sometimes. We checked with 3 or more doctors, not yet cure now one of the doctor suggest to take blood serology crp test in shows 18.8mg, so the doctor replied you have some allergy only and give medicine.
