Bumps After Pixel Laser to Tighten Skin?

I'm a 40 year old female and have had 1 in a course of 3 pixel treatments for skin laxity. Everything was fine up until 4 weeks after treatment. Now my once smooth skin is covered in hundreds of noticeable bumps. My questions are: 1. Will more treatments help or make the bumps even more pronounced? 2. How can I get rid of them? 3. Is this normal after Pixel and should I have been informed that the collagen the Pixel stimulates would form bumps? I'm obviously upset and depressed about this so any help/advice would be gratefully received. H x
