I have an odd swelling in the outside of my left knee. It tends to get larger when i run, but it does not really hurt. It can often swell just while sitting at my desk or at a restaurant for a couple of hours - when I get up it feels really tight tna there is a bit of soreness. When I reach down, I can feel a larger bump than usual. If I sit and cross my feet so my left and right feet cross under the chair the bump goes away almost completely. I have been told it could be an aggrivated IT band or hamstring but no one has been able to provide a firm diagnosis and hence no firm treatment except expensive Chiro that does not seem to be helping. Thanks, PDC
