I thought I'd try and get some help here (I've been googling and trying to do a self-dignosis via the net) before dragging myself to the doc. For the last 2 months I've had a pain at the side and to the rear of my knee...it seems to be brought on by the impact of running and afterwards it is sore when I flex my legs - especially if I put weight on that particular leg and bend it. I tried to locate the pain and can't fathom out if it is at the top of Tibia or if it is a ligament / tendon...it's not the knee itself - which even though they have been achey in the past and can be personal barometers in winter (!) they are fine now with the Cod live oil and Glucosamine products I take. The soreness / stiffness dies down after a day and I have binned the running and been out on the bike for some serious work... no problem there at all. Whether the different range of movement and the fact there is no impact on the area whilst on the bike means the problem doesn't flair up, I don't know...but on the 3 times I've gone out for a run to 'test' the injury, it comes back and I'm at a loss as to what it is or what to do - pure rest, no sport?? See the doc?? Chop the leg off?? Any help and advice would be appreciated...or I'll go and see the man and let him see what the runes say!!!
