First thing you should do is reduce inflamation. That means rest, ice and possibility anti-inflamatories. The next thing you should do is stretch it. ITBS is caused by your ITB being too tight and rubbing against parts that it shouldn't. I've had ITBS before and religious stretching usually does the trick. The best method I found so far is definitely using a foam roller: Get yourself one of these and do the exact thing in the picture. Good luck!

Here's my advice: You want to figure out how far you can run without it hurting. (for example, 3 miles.) And then run _less_ than that. (continuing example: 2.5 miles) Once it starts to hurt, you have run too far. If you keep running, it will only get worse. This is true specifically for IT probs, and most overuse injuries in general. (I learned this the hard way about ten years ago from tendonitis - not due to running, but it took me forever to deal with it because I didnt stop what I was doing!) Then, gradually start to build up. If you hurt after a run or during your next run, you are building up too fast. Now, the hard part is figuring out how far and how fast. And not getting too frustrated or going too crazy The thing that made the biggest difference for me was getting new shoes. Mine only had about 200 miles or so on them, but when I took them to two different (both great!) running stores, they both said my shoes were ready to be replaced - I guess 4-5 months trumped the mileage. Though my last pair of shoes seemed to die around the same age, so maybe I just need new shoes at fewer miles than most. Must be due to my ginormous weight. Ice and stretching are both really good. I was told to go see a massage therapist for a sports massage, but then I was told it would hurt. Alot. So I never made it. Cross train. Work on pelvic stability - especially abductors and gluts. Good luck and I hope you feel better soon!

I started back at 1 mile 3 times for a week. Then I increased to 1.5 M-W-F. Then I did 1.5 M-W and 2 F. Then 2 M-W-F at which point I started to hurt a bit and backed down to 1.5. So when I say slow, I meant r e a l l y r e a l l y s l o w! Yeah, it took forever. But it worked!!!
