weekly knee injury reassurance thread

Pulled...something in my left leg on my long run Sunday. Manifested by very sharp pain (almost nerve-pain sharp) in my knee to the inside at the end of the run...but as things have calmed down I think it's just some inflamed tendons and maybe an overworked hamstring. Nothing is swollen or acutely painful, so rest will cure it I think. I suspect the cause was tight hamstrings and tendons exacerbated by dead shoes and possibly by realigning my bike cleats to point forwards (I've been riding pigeon-toed for months...should never put your own cleats on if you don't know what you're doing). Replaced the running shoes yesterday.

I took a total rest day yesterday, and I'm redoing my schedule so there's no running till the weekend to give the pulled/inflamed things time to heal. Here's the question -- I know I can swim...can I ride the bike without annoying whatever it is I've done to myself? SHOULD I try to ride the bike and see if it hurts, or should I give it some time and just try to relax?

Thanks, all.
