A question we get asked frequently is why this is happening.
It could be for many reasons, one of the more common ones is called femoroacetabular impingement, basically what this means is the bone and the socket where your hip and leg meet, there can be rubbing of the bone which is where the pain stems from. Other things could be abductor tightness, so the muscles inside the leg near the groin. This can lead to them pulling and making it feel uncomfortable. Sometimes it could even be something commonly known as a sports hernia.
Ways we can help this?
One would be to get hands-on releasing those tight muscles and free things up. Two would be to strengthen those muscles doing the hard work. Three is simply stretching to allow yourself to get more flexible for more range and balance in your body.
