What does normal healing look like after a vascular laser session on the cheeks?

I had a laser treatment on my cheeks to make some little veins disappear 9 days ago. I was told that I might have a bruise or swelling. I had a big swelling for 3 or 4 days. Since then, I have had quite pronounced red marks on my cheeks and a some sort of bumps under my skin (which I can see and feel with my fingers). The personal experiences I read about only spoke of a slightly pinkish aspect so I don't know if I should be patient or worried, seeing no improvement...
