Am I having a reaction to laser hair removal? Could it be caused by photosensitizing medication? (Photos)

I had my first laser hair removal treatment 2 days ago without much of a consultation. I was not informed that I should have shaved first, and therefore had a few days hair growth which was not removed, nor was I asked about medications I'm taking (I'm on amitriptyline) or anything else that might be a contraindication. I woke up today with 6-7 pustules over hair follicles which broke open easily and now have redness and irritation in those spots. Is this normal? Should I stop treatment?
