y Dear Welcome to Healthcaremagic! You seem to be having an allergy or hypersensitivity to something that comes in contact with the right side of your body, mainly the upper half. The ear canal symptoms may either be unrelated to the condition or it is also possible due to dissemination of the process from arms to the ear. The commonest substances that cause this kind of picture are exposure to some air borne allergen while driving or sitting by the car window, a splash of chemical or irritant containing liquid or spray, a chemical that you handled as a result of your household work or occupation etc. Clobetasol is steroid that will control the symptoms due to allergy but it will ultimately be your interest to find out as to why this happened. To explore the reason the first thing that you do is to sit down and take notes of everything that you do, handle, and every place you visit. Then try to shortlist the suspected causes of exposure . after that eliminate the shortlisted culprits and see how do you feel. After a week or so, you might like to confirm your earlier results. Now you start introducing those items one by one carefully noticing the changes that appear after every step. That way, you will be spared of the burden of tests to detect allergies at least to a major part. Taking ant allergic is good idea to control symptoms and might help you until your next appointment. Best wishes!
