not blowing this off, and good idea to see a doc., sounds like an existing condition that has flared up. after competing, i really have to watch my sodium intake cause my ankles will disapear lol.. feet go numb, the whole deal..the fluid build up, along with gravity can cause terrible edema.. have you had any rapid weight gain recently? and some, myself included w/ my lower legs- just have poor circulation in the extremities.. not life threatening, just have to keep an eye on it. i even got a foot doctor buddy of mine to get me a pair of those support hose.. u know- the ugly ass tan colored socks that come up to your knee caps? lol.. they look whack, but work great in improving circulation..you should see me pimp em' around walmart.. funny AS HELL. hope the doc visit goes well...
