Blisters and pain up and down arms after IPL freckle removal treatment. Was I burned? (photos)

I had an IPL freckle removal procedure done by an RN and had some pretty intense pain after (could barely drive home). The pain went away after several hours, but I developed bumps (blisters?) all up and down both arms. The nurse told me these weren't actually blisters, and that this was to be expected, but I just feel a bit uncomfortable with her answer . . . especially after googling around. (Normal patients seem to experience minimal pain/swelling?) Photo attached. Does this look "normal"?
