Ive been to the best dermatologist in my area. I have a rash that was checked on my inner thigh by my trunk. Although better, my itching does it no good. I have used cortizone cream, every other kind of cream, calcium sulfate baths, etc. It is much better than it was but still not healed. I have had small bouts with psoriasis in the past it is in my family. Male 65, fairly athletic, run almost every day. 6 2 . 205lb. Healthy diet. low in carbs, high in protein and vegetables.
