Laser hair removal burn complications (Photo)

I am a 21 year old male, 5’11”, 160 lbs, fitzpatrick type III. In 2020 + 2021 I had laser hair removal on the buttocks + anal region by a dermatologist. I began to burn after several treatments. I informed my doctor and at my next treatment I got a blister. I then stopped altogether and have been dealing with bleeding and pain in the area ever since. I exercise, eat plenty of fiber, and stay hydrated, but frequently experience discomfort + occasional bleeding while using the bathroom.
