I can't believe I hurt my knee tonight. Normally, my knee will get sore during yoga, or other activity, but tonight I think I really hurt it. I was trying to keep my leg straight during a hamstring stretch, and I think I hyperextended it. I haven't been able to fully straighten it all night. I am hoping that if I take an ibuprofen and go to bed early, it will heal overnight. I'm not sure if it's possible, but I am hopeful. Cross your fingers for me?
