How Long for Inflammation to Subside After Q-Switch Laser?

My dermotologist used a q-switch laser for brown spots on my face. One week later the scabs fell off naturally and the spots were a light pink. I saw the doctor the following week and he said it was just inflammation and that it would fade in another week or so. It's now been two weeks since then and the spots are getting darker - reddish in color. How much time should I give it until the inflammation is gone? I'm so nervous that I just traded ugly brown spots for ugly red ones.
