After 4 years, redness, shedding and skin swollen in the donor zone

Hi friends I had hair transplantation in November 2019 because of the corona PRP was pretty delayed this year in June this year PRP and the ear level of a very small skin because I went to the center where I had hair transplantation. They did PRP and intervened in the area of swelling. After 2 months, swelling and redness grew more. My psychology is broken, did anyone come to him or how did you follow the road. Good evening.
