My Hike "Gone Wrong"

After wasting away most of the day doing much of nothing, I opted to head out at 430 for a "quick" 11 mile hike on one of my favorite trails in the Pigeon River. It is an easy trail, so I figured I shouldn't have any problems getting back before dark. All was going well for the first several miles, I was making great time. Than I noticed a little bit of pain in my right knee. Thats odd, I didn't remember hurting it somehow. I did stub my toe on a root, but didn't notice any pain right away. Unfortunately, the pain in that knee got continuously worse. As long as I kept moving, it was tolerable. But to stop, for even a couple of seconds and try to go again, the pain would be more severe. Of course I was alone, way out in the middle of the woods, and had no other choice but to continue hiking. Slowly. Fortunately I made it out before it got too dark. It is always much darker deep in the woods since the little daylight that there was, was not coming down on the trail. I felt tired, sore, vulnerable and helpless. Now that I'm home, I've popped 800mg of Motrin, iced the knee, took a hot bath, but still it hurts like a b***h to stand on that leg. Imagine my dilemma. Two more perfect days before I go back to work and I'll be unable to hike, bike or swim. All my favorite past times. Whats a person to do?
