Are you doing any core and hip stabilising work to help with the ITB? When I had ITB several years ago, Katie Roby advised me to do these to fix the body's imbalances.
ITB will not get better if you don't improve your core/glutes and stretch your bum end of the ITB. Leave the knee pain area alone (or ice). Gentle foam roller of ITB to loosen the sheath. Better to do shorter runs and lots of stretching and strengthening until you have got to a managable state.
Yes, have been doing the above, reasonably consistently, though still not as much as ideal. It's not sore enough to be painful, but that's probably because I've been aware of it and holding back when it does start to become sore.
