Get the book I suggested above, it has some good stretches and exercises that may help. Also see a PT to help with other issues you may have, it doesnt sound like this is caused by cycling but maybe aggrivated by it. On line medical help is never going to fix you but with a PT and the above book you have a good chance. One thing though, dont ignor it, that is the kind of problem that wont fix itself and can actually become quite serious if you try and just ride through the pain
