My son 6 yrs old had a pimple  right above his penis.  Its in the fleshy area.  The Dr. thought it may be a bite and prescribed antibiotics and a cream this Thursday past.  When I brought him in there was a red dot with an area of redness around it, (like an infection).  After applying the cream the all the redness went away but not the pimple.  Just now I notices the redness is coming back.  It doesnt hurt him, but sometimes I catch him itching that area.
Hello, Welcome to Chat Doctor, The symptoms of your son suggest me that he may be having some fungal infection. The fungus is the normal comedians of this area, which will be kept under control by the useful organisms whenever there is a change in the environment this fungus will activate and produces the symptoms of itching and pain. Your sons symptoms requires physical examination to find out the actual cause for the symptoms, and then it can be treated appropriately. For his symptoms I would suggest you to followed that area clean and Chat Doctor.
