Good morning doctor. I m mrs.Kalpana here from chennai. I underwent a surgery for benign tumour on the left side of the head near 6th nerve (left eye). i hv already suffered severe itching on the scalp of the surgery region,not exactly on the sutchers side but on the front left side of my head. after itching, the scalp became red n it is dried with black thick n dried skin. im unable to comb that side cos of frighten. i would like to know the main causes for this as i get this for the third time. whenever i get itching it is not controlled by me. with tears i scratch it to the core. pls advise me. i was already given 5 tabs for the same previously. but now it is very difficult for me to go to my hospital all the way from my home in this heat weather. And ofcourse money is the main reason for the same too.
