Can you get massage? Sounds like something attached to muscle is tight, and that being the case, there are things (massage) that can help, as well as stretching and strengthening of course.
As I get older and rustier, I have increasing trouble with tight tendons that sometimes pull my hip so it doesn't track correctly. If I stop immediately, grab a lamp post and swing my leg forwards and pack until I feel it click back into place I can carry on running, no problems. Ignore it and I am lame indeed. Usually so lame within 50metres that I can't run at all, so maybe not the same thing. (And I stay lame for 3 days if I am so foolish as to try and run.)
But in answer to your question - probably there are ways round it. Get some help?
