Not liking my knee today

I don’t know what is going on, but my knee is really bothering me. I don’t know that it is actually a knee problem or a hamstring thing, but it has me questioning riding to work today. It is walk to school Wednesday, so I think i will give that a go and make the decision when i get back. I did commute on the fixie for the first time on Monday, maybe I just need gears today?

I want to ride… Just don’t know if it is my best idea.
