Red, spreading rash 6 days after Yag laser resurfacing (Photo)

I had yag resurfacing done 6 days ago. My face was almost completely healed, and only a little pink. Yesterday morning my right cheek started to itch and got a little red, then progressively got worse through the day and into the night. I got about an hour of broken up sleep, it itches so bad. It has also started to spread to the middle of my forehead and to my left cheek. It's Sunday, so my doctor isn't in office today. Should I go to urgent care? Or can this wait?
