Broadband Light: Do red spots get brighter and darker before improving?

Had a BBL yesterday for brown and red spots/caps on face. The red spots, especially on my nose, are now brighter red, with new bright red spots that have emerged on the nose that were not visible before. Dr, used 2 filters on the BBL and then used a 3rd laser on the red spots on my nose and other areas to "coagulate" the spots. Is this typical to get worse before getting better, and if so, how long would I expect to wait for improvement? I'm worried the treatment only made things worse.
