Sir iam suffering from scabies even I used medicines for a week iam feeling itchy rashes and itchy pimples like on my penis please sir what should ido?

It takes 2-3 weeks. It takes 2-3 weeks for scabies symptoms to subside after successful treatment. Even though the treatment killed the scabies mites, your body is still reacting to the dead mites, eggs, and droppings in your skin. Just wait it out; your symptoms will clear up in the next couple of weeks.
