Knee surgery

I'm in hospital following surgery to remove torn cartilige. I opted for a spinal injection instead of a general anaestetic. I watched the op on the screen and talked to the surgeon. Some cartilige was cut out but also a repair was made to another area the surgeon was unhappy with. As a result i can't run for 6 to 8 weeks. I have to stay in as the anaestetic failed to wear off. I'm still mostly numb 7 hours later. I've had a catheta fitted as i have no feeling, couldn't pee and was in pain. I filled a full litre in 10 mins! Too much information? Probably. I should be released tomorrow. Thanks for all the well wishes on facebook everyone!
