Hoping CP can guide me a bit here... I've been running since 2010, usually 30-40 miles a week. For the past four months I've been running on the wrong shoes, and it's messed up my biomechanics. I now get stiffness in my knee on my left leg, which is causing tightness in my upper leg (especially IT), and is now affecting my glutes and lower back. Looking for a plan to follow that will ease it back to normal, if such a thing exists. Regularly using foam rollers and lacrosse balls, shifting my workouts away from running to swimming/biking/stairs. Also going to look into the knee injury clinic at U of C. Any help would be great!
