Just common sense

"Doctor you are genius, your diagnosis was absolutely correct, see i am all improved". He came with a wonderful smile on his face this time . I remember last time on his first visit he was quite apprehensive regarding our diagnosis and treatment.
                          He had very thick skin lesions of lichen simplex over his legs and he had shown to many renowned dermatologists .
                          I wanted to tell him that neither our diagnosis nor our treatment was unique . Skin was so thick that the same medicine in creams or tablet forms was not penetrating in. So all we did was that we injected the same medicine inside his skin lesions. Just common sense no rocket science.
