I jumped on the bike this evening for a 45 minute, high speed ride. All day my left knee was sore. It has been sore off and on for a few weeks and I cannot put a finger on it. It seems sore during normal hours, walking climbing stairs, kneeling. The one time that it doesn't ever seem sore is when I run, workout, bike, etc.
I am confused by this because it seems to not be exercise related. I am hoping it just goes away. The only thing I can think of was that I was doing too many box jumps a couple of weeks ago. Although a great exercise, box jumps can be hazardous to knees. I gave those up and haven't done them in about 1 1/2 to 2 weeks.
I am keeping my fingers crossed.
