Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain eruption of recurring red itchy bumps over the legs for which you are advised betnovate that is a steroid ointment and epaderm that is an emollient/lubricant can be due to common causes like: -CONTACT DERMATITIS that is an allergic reaction which occurs when skin comes in contact with certain agents that your body is allergic to like skin cosmetics, detergents, soaps, fragrances,leather, latex, poison ivy etc.. -FOLLICULITIS or generalized hair follicle infection caused by Staphylococcus bacteria leading to formation of painful bumps over different parts of the body.. -Another cause can be food allergy or side effect of medicines.. You need to consult an Allergist or an Infectious Medicine Specialist and get evaluated and a thorough clinical evaluation and investigations like blood tests to rule out allergies and infection, micorscopic examination of scrapings from lesion can help.. As of now you can take anti allergics like benadryl for relieving itching and do cool compresses over bumps.. Once the cause is ruled out it will be treated accordingly.. - In case of Contact Dermatitis you will be advised anti allergics, topical steroid ointment application and also avoiding exposure to allergen when it is ruled out... In recurring conditions Immunotherapy will be advised to you.. -In case of folliculitis antibiotics oral and topical and topical steroids can be advised along with anti allergics to control itching.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
