Hello I Have Been Experiencing Pain In The Side Of

Hello I have been experiencing pain in the side of my left thigh when squatting and walking up stairs. I have gone to two orthopedics and they both seem to think that my it band (tfl) is tight, but I've been foam rolling and stretching for some time( months) now and it hasn't disappeared. I don't believe my glute med is weak...I'm a pretty strong guy...what else could be the problem?
