Well, I've gone and done my back in. It may be a herniated ("slipped") disc. Did it playing touch football for my Wednesday night team, I Need a Rest.
10 minutes to go in the last half, I made a nice run around their winger, and stepped inside one pursuer (who then fell over). Charging toward the line, I heard someone thundering up directly behind me, so I panic-dived for the line. But I didn't get to reposition the ball in both hands out in front of me - I just flopped on it. I was over the line, but my pursuer was going so fast, he tagged me as he skidded past, and off the field, almost into a pole.
I was winded immediately and felt a little worse for wear, but kept playing until the siren. It wasn't until I sat down in the car that I felt my back twinge. It pained me to drive home, I limped into the shower, then I installed myself on the couch, knowing I'd done something wrong to my back...
So I've been off work for a week now; can't stand upright fully, instructed not to sit at all and completely dependant on warm wheat bags, pain-killers and my stockpile of unwatched DVDs.
My physio says I'm improving and I feel that I am aswell; but I'm a long way off being 100%. I may be able to return to work soon, but with a strict list of parameters about my seating & activities. Touch footy will be out for quite a while. I have daily sessions that involve poking, prodding, sharp objects (acupuncture needles), electrocution (TENS machine) and searing heat (warm wheat bags). It's like a medieval torture chamber with a modern spin.
It does make me feel better after each session though. My physio and I have an ongoing competition to see how many time she can make me squeal like a little girl. (Little does she know that's my normal squeal).
This is a somewhat-related to an injury I did last year lifting stacks of chairs - 20 years of bad posture and sitting (working in IT...) means I have certain under-developed muscles, and some nerves (sciatic, I believe) that aren't as stretchy as they should be.
Anyway, we won our touch game 8-1, anyway. It was raining, the field was sodden and our opponents were a man down for 50 minutes of the game, and we had our freakish ring-in Alan who can dances around opponents as if he was performing in Swan Lake; but we'll take it :)
Normally, we celebrate draws!
(I still wish I'd gotten that try I did my back on...)
