Food for thought...
You have an asymmetry otherwise you'd have symptoms on both sides.
If you always run on the same side of the road, one foot will always pronate or supinate more than the other.
Do this:
A single leg squat on each side and compare symmetries in the knee, hip, and lower back
Stand on one leg with hands behind head and other knee raised as high as possible for slow count of 10. Compare balance, wobble, knee position of both legs, hip position of both legs, and lumbar posture
Perform a maximal single leg long jump and compare distance and landing mechanics on both sides (by the way, my guess is that they tested your quad/ham strength while sitting on a kin-com, biodex, or cybex and compared sides. This long jump test is infinitely superior to any isloated test sitting down)
Any symmetry in these test will need to be fixed to fix your problem.
Dead numbness (like you can stick a pin in it and not feel it) is a neural compression issue. Pins and needles feeling is a release phenomenon preceded by a compression.
If you have an IT band problem it is a symptom, not the cause.
My money is on a weakness/coordination issue. Get someone with a good set of eyes and knowledge of corrective programming to help you. I'd also cut back on running before you are injured and cannot run at all.
