<human>: Can you give me the gist of the text in a nutshell?

Anyone got them?  It looks like I'm getting it.  Possible causes: I recently increased my mileage (marathon training--increased my mileage from 15/20 mpw to around 30 mpw).  My left femur is 3/8 of and inch (about 1 cm) shorter than my right femur.  I suppose there could be some other cause too, but that seems less likely.  I run with good form and I never heel-strike (I'm not sure if that even matters for this condition).  It is ONLY my left IT band that is giving me issues.

My Question: I've heard about foam rollers, the cane, the stick (the rock?).  Anyone use them? Know someone who has?  All things being equal, I'd get the stick, because I can see myself using it every day.  Advice?

I've been doing various stretches for it since last weekend.  It seems to be helping.  I realize that this issue probably took a month or two to develop, so 5 days of stretching won't cure it.  I will continue to stretch.

I talked to a physical therapist today (I work at a school).  She confirmed that I'm doing the right stretches.  I asked if I needed to stop running (it doesn't hurt when I walk, only after I run for over an hour).  She said no, but that I should avoid hills, going up or down. And run shorter distances.  I'm a little surprised. My feeling is that I SHOULD rest, even if I don't really want to.
<bot>: HOW TO FIX IT BAND.  FOAM ROLLER? THE STICK? SHOULD I AVOID HILLS/CUT-BACK MY RUNNING/REST?
