Pain on outer side of knee, hurts to walk?
I usually run three times a week, and I run about four miles every time I run. A couple weeks ago, after my second run of the week, the outside of my knee hurt pretty bad. The next day, the pain was so bad that I could barely walk to class. By the weekend, the pain was pretty much completely gone so I ran again, but during the run the pain came back so I stopped. My mom recommended that I use the stair climbing machine instead of the treadmill until my knee healed. After three days of using the stair climbing machine, my knee was worse than ever. Now it has been painful to walk, and the only exercises I've done over the past four days is walking my dog. Have I done permanent damage to my knee?
