Yeah, sorry – your plans for Monday are pretty well u/s if they involved a bike. The grades refer to how badly it's gone, IIRC one is a bit torn, two's a bit more torn and three's severed. Mine's completely gone and my right arm hangs about an inch lower at the shoulder. It's a bitch for a long time, although there are surgical options. I was advised to leave mine, and some years on I don't even think about it and it doesn't have any impact on me day to day.
I was back riding very quickly, but like I said, I couldn't steer worth a sh1t(some may say there was little difference). Embrace the physiotherapy, it does make a massive difference, and if you'd like any info, just drop me a line.
