Rough and itchy patches. Should i do, ?

I have a history of skin disorders though I take all possible precautions like frequently taking a bath, changing the underwear etc. Every summer I end up with a fungal infection that in my groin area which may even spread to parts of my penis.it is extremely irritating and very itchy. I end up consulting a doctor every season and have been suggested onabet ointment, candid ointment terbest and teczine tablets in the past. Though these medicines give me relief, the same situation arises in the following season. I have also been using an antifungal soap called novale.. Can someone kindly suggest some alternative medicine for this season, one that can get rid of this menace permanently. Or suggest which medicines of should be using. Lately, I have also developed itchy and rough patches on my forearm and elbow, they are red in color and like very minute pimples. End up bleeding if you scratch too much. What should I do,? I am more concerned about the infection in my groin. Pls help.
