Thinking about that particular injury, it might be that certain kinds of compression gear might be helpful- it's a thought, at least. Not really sure if it'll be worth it, though.
The CW-X tights and Zensah stuff are only marginally helpful. But the Zoot stuff might be better- at least, according to their literature, it might.
I'll have to give it a try and see how it works. If I do, I'll probably go on about it. If it doesn't, and I really hunger to do road races again, I'll probably have to consider surgery. argh. :P
