My sister has a swollen foot, but the whole thing isn't swollen....it is just the top of it. Her toes and ankles are fine. It is very defined to just that area. She doesnt want to go to the DR because they will probably tell her not to run, and being her, that won't happen. So she doesn't get it checked. There is no pain, and the swelling has remained the same for a long time now. Never gets swollen more that the top. She's had it for a long time and I'm worried it is something more than just a swollen foot. Any comments welcome. Thanks.
