Knees pain

[Nathan Rubin]

I am riding hard Enduro twice a week.
Every sessions lasts for about 5-6 hours.
When riding I am pinching the seat with the knees and keeping the knees right above the footpeg. Just as Gary Semics says.
Last month knees pain began to develop. The pain comes from the inner side of both knees exactly where the knee touches the seat. What seem to be a problem? :bang:

Overuse, take off a few days then make a pad to protect those points.
