Can anything be done to get rid of the red, rashy bumps that appeared on my face after blue light with levulan? (Photo)

I had blue light treatment with levulan only on my forehead a few days ago. Approximately 18 hours after treatment, my forehead broke out in these red, rashy bumps with a few milia mixed in. I did not have any of this prior to treatment. Can anything at all be done to rid myself of these awful bumps? The picture below does not really show the bumps that well, but they are very present. It does not burn or sting. Also, I should mention that I have extremely sensitive skin. Thank you.
