I have recently taken up running to try and decrease my ever expanding girth. I hate running to begin with, so thought that I would do some sprints, to not put my aching Achilles tendons though too much strain. Well I did my first sprint at about 80 to 85 percent full speed. This felt good. I walked to my original starting point to catch my breath and started my second sprint. I felt great. I wasn't straining. I wasn't winded. Everything was fine. I was coming up to the finish line I created and SNAP!! CRACKLE!! PLOP!! The PLOP is when after I pulled my hamstring I came crashing to the ground. So I was lying in the middle of the street in front of my house thinking, this is not good. I think at some point I need to get up before a car comes and how am I ever going to make it to work. After a few minutes I managed to stand to my feet and move off of our communal driveway. I thought of crying out for my wife to come get me but realized that everyone in the house was asleep and I was on my own. I slowly make my way onto my patio and into the house. My heart is racing and I feel nauseous. It hurts to stand and it hurts to sit. I lie down on my living room floor until after the pain in my thigh subsides a bit and my breathing becomes more regular. I then get up and attempt to mount the stairs. First I tried to walk up but as soon as I put any weight on my leg it buckled under the pain. Strike one! So then I tried to crawl up the stairs but my leg hurt if I bent it. Strike 2!!! I finally devised a plan whereby I would climb the stairs by sitting down and pushing up with my good leg. I did this until I reached the top of the stairs and then used the banister to pull myself up. Victory was mine.
