I have had a swollen right foot (Top) for about 5 years now (I think following a twisting of some sort on a bouncy castle), it has become progressively more swollen during the course of this time. There is no pain but it is becoming unsightly. It feels quite spongy on the top. I am 5ft, 5 , 8.5st, run regularly (30 mins, 5 days per week) and am in good health otherwise.
