Hi, Bone spur may not cause a swelling .. Swelling of legs could be beacuse of many reasons.there are a lot of reasons for this I can come to a conclusion only if you can provide me with details like age, sex, any shortness of breath, any decrease in urine output and images of the swelling. It will subside on its own if it is due to long standing or travelling for long distances. Take tablet serratiopeptidase+diclofenac after food for a few days to get immediate relief. Visit a physician if problem persists Hope I have solved your doubt...i f you have any further questions I would be happy to help you..
