Hi Ally, Welcome and thanks for posting your query to HCM. I can make out the level of stress you are passing through because of the undiagnosed rash. You have not described about the waxing and waning of the episodes or any relief from the rash in these 6 months, recurrences and or any relief of any sort from various type of treatments. Anyhow, after reading your problem there are many a possibilities which you have already mentioned. Your diagnosis can be made by simple investigations like KOH mount, Culture and sensitivity for bacteria and fungus and last but not the least by simple biopsy (most diagnostic). I can make out three important diagnosis from the query: 1. Lichen simplex chronicus: A condition of thickening of skin due to continuous itch -scratch - itch cycle. 2. Infected Scabies: Condition caused by infection by a mite which causes mainly nocturnal itching 3.Resistant Tinea cruris : Fungal infection of the area which is not curable by application of common antifungals. This requires latest antifungals to which the fungus will respond. You should meet a proper dermatologist who can diagnose and treat the possible problem at the est. You stop all the cream applications( as multiple application s also aggravate the situation) and can do simple sitz bath ( luke warm saline water compression) for multiple time a day and can take round the clock non-sedating anti-histaminic coverage till the time you meet a dermatologist. With best health wishes, Dr Sanjay K Kanodia MD ( Dermatology and STD/ Venereology)
