How much are you running at the moment?

I know its not ideal but you may need to rest it then gradually build up again. Its taken me over 4 months to be confident with mine after my last bout.

I had to rest for a month then gradually build up. Everytime I felt my knee starting to even feel as if the sensation of the pain was about to start I'd stop running and walk back. I'm now back to full training except my calf has pulled so not because of that. The reason for stopping is if you carry on you end up causing more irritation. The more irritation you create the worse the problem becomes

Other things that might be worth a try are anti inflammatory gels over the area of pain or Ice. My method of icing would be to get one of them polystyrene cup jobbies fill with Water and stick it in the freezer. When frozen peel back the poly to reveal the ice then rub directly onto the area for a maximum of 5-10 mins. Be warned Ice can leave a nice burn if you keep it still. Repeat as and when but no more than once an hour.

Just keep going with everything. ITB probs are a right bummer to shift
