Is it normal to have feelings of pin pricks & needles, and feelings of burning up the leg after a week of Laser Hair Removal?

I had laser hair removal on my legs last Thursday. So it is exactly a week today. I'm still having these feelings of pins & needles, and some burning up the leg. It feels like it is getting better, but I still have them. How long does the skin take to heal? What would assist in this healing process? And is it better to wait longer than 8 weeks for my next session, to prevent any markings on the legs? Thank you doctors. This website is very helpful!
