A couple weeks ago I was out on a long ride (100 miles) and started to experience knee pain after some steep climbs. I think climbing out of the saddle was the cause. I think I was pulling up too hard with the trailing leg.

The pain was originally on the inside and outside of both knees, most pronounced on the left outer knee. The pain got pretty bad at mile 75 but I was 25 miles from home so ... oh well. This is a sharp wincing pain, not like the duller knee tendinitis pain I am more familiar with.

I took a few days off and went out for another long ride today. At about mile 50 the pain started slowly again, only on the left outside knee. It began with hard efforts but didn't bother me at normal power <350 watts. As the ride continued, it got worse and worse. Sometimes it wouldn't hurt for a while, and other times hurt real bad. It would hurt under no load, under heavy load for sure, and of and on at intermediate powers.

Anyone have a similar experience or have any suggestions? I took a big dose of ibuprofen when I got home and am icing it now. Sorry for the length of the post.

TIA
