I tweaked my right knee the other day, slow log crossing gone wrong! So far they think it's just a good old sprain, but if it doesn't improve in 2 weeks (off work) they will send me for MRI to look for more damage.
I'm quite a bit more mobile already, hoping this doesn't interrupt my biking season for too long! My new crutches are covered in MX / sled stickers! (I knew I was keeping them for a reason!)
