I have had a red spot on the penile glad for three weeks. It appeared overnight. I have not been sexually active for two years. I have tried neosporin and aquafor, but neither appear to get rid of the spot. For the past three days, I ve used cortisone, but the spot remains as well. Sometimes it turns more pink as if going away, and other times it gets red to purplish and becomes a bit shiny near the center of the spot. There s very rarely itching and never discharge around it. However there s a a bit irritation to the touch on the occasion (when it s darker red). It is uniform and about 1-2 cm in diameter. What are some options for what it could be, and what are some potential treatments?
