Since 2004 I have periodically had severe swelling in my feet, ankles, legs, and knees. These "attacks" just come on very quickly and usually last about a week or so. I always have atleast a little swelling around the ankles also. My fingers have also turned red around the nail bed on the first couple of fingers, the pinky, ring, and middle. Also, my big toe nail on both feet have started to loose pigment, turning almost white underneath. I have seen a doctor and would like to know your opinion of what this is or could be. Thanks so much!
