Hi, my 4 yr old son had a tiny bump on his scrotum (looked like an insect bite). The next day his scrotum was red & swollen, & sensitive to touch. I applied an anti itch cream & asked him not to scratch. Today his scrotum is purple & not as sensitive as yesterday. Should I be concerned?
Hi...you should definitely be concerned, and I suggest you get him to the nearest emergency room immediately. Purplish discoloration of the scrotum is not good at all. Even though he is not in pain he might be in the latent period.  I suggest you get him examined by a physician immediately. Regards -
