Is this ointment good? Will it damage the hair? (Photos)

Hi,I started feeling itchy,when I scratch my neck, I feel I want to scratch more and more eventhough I didn't have hair transplanted on neck. At around day 17 or 18, I felt my chin area is so hot and I took a pic, I saw something yellowish in some areas, hair coming from it. It's like pus. Asked my doc on Whatsapp since he's in a diff country,he says use Fucidin cream, since I don't have it, I have Fucicort, he said it's the same! Two times a day for five days. I'm nervous if i lose hair.
