Petechiae (Red Spots) Normal After Laser Resurfacing?

I had full face quite deep tradtional CO2 Laser resurfacing 8 weeks ago for acne scars (full face bar eyes), i still have some mild swelling in lower cheeks, after being sick last week i developed what i believe is petechiae, on upper cheeks/temple which are slowly fading. i am trying my best to sleep on an incline to help reduce residual swelling, but wake on side sometimes, but i am still getting odd areas of petechiae in random areas, they appear in a morning, so must come in night? (i was getting this pre sickness event as well). is this normal & why is it doing it?
