I was out doing my usual 25 min LISS Run, I varied between running from the ball of my foot and the heel, as I didnt know which was more benificial, something I may regret now, but the next day the insides of my legs/knees have become sore and when I attempt to run generally at a slow pace Im somewhat restricted to increase the pace.

The image shows where my discomforts are orginating from.
