Pigmentation marks and irritation after Brazilian laser hair removal. How can I treat them? (photos)

The day of my Brazilian laser hair removal I left the office with dark marks all over the area that was treated. Its now been 10 days since treatment and they are still there! These are marks & not raised bumps. They have not faded at all. I also have extreme irritation and pain in my anus area which was also treated. So embarrassing lol but so painful! What could be causing that? Any treatment advice? My esthetician told me this was normal and would go away. I know this isn't a normal reaction.
