Knee Issues?

I think I'm going riding this weekend and I was wondering about my knee. I rode on Saturday and early in the day I landed hard on my tail and it made my knee feel pretty bad. I rode for the rest of the day because I wouldn't be able to ride during the week. It got worse through the day and for the next two days it hurt mid step. After hurting for two days it feels fine, I was just wondering if I did anything to it and if it will be fine for this weekend.

Probably just a strain if it only hurt for two days. Take it easy on the first set or two and see if it starts hurting. If not enjoy your weekend. BTW, you should stretch and warm up a little before you ride.
