Hello doctor, I am facing itchy and bumpy back with small pimples. This issue raised after I shaved some area of back with razor. It causes high itching and bumpyness on back. My family doctor consulted me with terbinafine tablet & creme and keto powder, but this helped me to reduce itching for a small period but it started again after some time. Please suggest me tablet or cream for this. Here's the image for your reference.
