I had ITB syndrome too a few years ago and it also took me about 6 months to get rid of it entirely. mostly I think, for me, because I didn't get on the foam roller band wagon right away. what do you attribute your recovery to?

back on the bike I would caution to stay away from
cold temps
gearing too high
I forget the 3rd thing sorry, maybe saddle to high?

anyway, take it easy and build up your strength if you haven't been using an indoor trainer

welcome back! have fun!
