a horse stepped on my foot about three years ago and hurt it. I didnt go to the dr with it and it never did swell it just hurt. It finally went away and the last two years it feels swollen off and on and I put it up on a pillow and the swelling seems to go down but within a day or two it gets a little swolen again. I repeat the process and it goes down. This seems to be happening more and more and it did the samething last June as well and then finally went away for a year buts its back.Could this be arthritis developed in the foot causing this from an old injury. It doesnt have any symptoms of blood clot or anything like tht and when I put my foot up for awhile the swelling seems to go away for the day. Does anybody else have a old injury that does this?
