Hi all, I hope some of you guys can help me here. I started cycling about ten years ago but had a few years of (relative), inactivity due to having kids, moving farther away from work, etc - but I've been making a real effort to get back on the bike REGULARLY of late. All is usually good but I sometimes get a pain in my left knee, right in the side of the joint at the outside of my leg. If I cycle on it, it gets worse and worse until I can't cycle any more as the pain trevels around the knee and down my leg (it actually forced me onto the train for the second half of my journey home from work today, and I was not happy). If I wait a day or two, it seems to go away but there's no telling when it will resurface. My friends say I cycle too far but I don't agree, I do 60 miles a day but it's usually only two or three times a week. Some suggest I take up swimming but I don't want to and I doubt it's much lighter on my joints than cycling is. Have you any ideas what it might be? Cheers, AM.
