What could it be if having swelling in the outside of knee which grows when running, sitting?
Patient: 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 Doctor: Hello,The swelling on the outside of the knee that grows on sitting can be due to an inflamed bursa. You need to get an MRI scan of the knee done for a proper diagnosis.Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Praveen Tayal, Orthopedic Surgeon
