My name is Sagar and I am a 22yr old male, 5'11", 182lb.
In June of 2013, I started doing some stretches to improve range of flexion of my knees. Around this time, I started feeling a sharp pain in the anterior and lateral part of my right shin ONLY when my right knee is in flexion (approx 100 degrees into the flexion). Also, this pain becomes more pronounced if during flexion, I point my toes straight forward, rather than at a small outward angle. This pain originates just below the knee and goes as far as my ankle on certain occasions. It does not pain at all when I sit, stand or squat with a 165lb barbell (I squat until the angle between my shin and thighs is approx 90-80 degrees). There is no pain in my knee, only the shins.
This pain reduced slowly since it started, but even after a few months, I still feel it when I try to flex my knee towards the end of the range of motion. Any help would be appreciated.
