I was having a sensation on the top of my penis so i visited the doctors he gave me some cream for a yeast infection the sensation has gone but now i have began to notice other itching and redness on my groin and on the under side of my penis right up the center it kinda looks like the redness is following a tube from my groin to the tip of my penis but its on the skin. Really cannot afford to go to the doctors again if i don't have to so trying to search for answers first. Another thing i noticed i did have a pimple like bump come and go down there.
