What Causes Tingling Sensation And Pain In Upper Thigh?

Hello,My name is Sam,In my upper leg's between my groin and knee,on the outer sides of my legs,I have a burning tingling,kinda cold sensation,this morning I kinda stretched my legs befor I was reddy to get out of bed,,It felt like I had a stabbing pain in the problem spots on my legs.This has been going on for a very long time,Today is the first time I had the stabbing pain,but now its getting worse.The place's on my legs where the tingling is,are about as big around as a large grape fruit.I mentioned it to my Dr about 2 years ago,,She didn't say much about it at the time.
