Skin peeling off penis and scrotum.

Skin peeling off scrotum and now it's raw and red and even foreskin is tight to pull back and inflamed and sore/raw to touch for couple of days lately. I had applied neosporin ointment but got no relief. I maintain good personal hygiene and always wear loose cotton undergarments. Last time I checked my sugar levels were in range but it was around 6 months back. I think I will go for blood sugar tests (fasting and PP) but I want to wait for some days because I have just completed a course of steroids for my asthma and sugar level might be elevated. Please suggest some medicines to get relief from the pain and discomfort. I also wanted to inform you that I am a patient of acute Asthma and allergic to asprin & other otc pain meds. I have just finished a course of Defcort 6mg yesterday. Currently I am taking Abphylline 100mg caps 2 times daily. Seretra 80mg tab once daily, Theo asthalin 4mg thrice daily and L-montus tabs at bedtime. Asthalin inhaler used several times daily.
