Tuesday this week I went for a 46 mile (33 of that with a group) ride and developed a pain in the tendon on the inside of my left leg behind the knee. I'm not sure if it is the tendon or not, but it hurts where the knee bends on the inside part of the leg. It hurts when pulling up on the pedals and is painful when riding. Has anyone had this happen? How and when should it go away? What treatment will help to heal this? Thanks.
