I think. I've had HB for 3 months and have been unable to run and it's been quite painful at times, no way I could sleep on (I still can't), but it seems to be getting better, slowly and I've run 3 times this week with no real after effects. I thought I'd post what has worked for me and what hasn't as I know there are a few peeps that are plagued by this. Firstly what has probably brought this on is weak/inhibitied glutes, working in an office does not help, then I did a 70.3 in racing flats and bam welcome to hip bursitis...

what hasn't worked:

- 2 x cortisone shots, 1 guided by ultrasound. They can be very effective for some people, but for me it had no effect whatsoever, I guess it's a bit hit and miss
- rolling glutes, ITB etc
- stretching
- NSAIDs, ice - did nothing to alleviate/reduce the pain
- rest

what has worked

- I noticed an almost immediate change after doing two exercises, the bridge and the clam, both recommended by a poster in here (can't find the post, but I owe him a beer!). The clam, especially really targeted, very specifically, the glute medius (not sure if that's the right name) and I'm guessing for me that was the problem. A tight/inhibited glute medius
- getting up regularly at work, not sitting for extended periods of time. I'm going to get a sit/stand desk.

I probably won't fully recover for a while yet, but being able to run pain free is just great :)
