Ok my father in law had cardiac stents put in nov. 17, nove 21 his foot starts hurting, swells up and he cannot walk on it.. It has turned different colors, breaks out under the skin.. He has been told it could be RSD, but no one knows for sure.. He has been in the hospital and multiple doctors have looked at it.. NONE of them know what is wrong.. He is a very active man..farms for a living.. The past 6-7 weeks he cannot even get up to go to the bathroom by himself much less work. Does anybody know if stents and RSD go hand in hand..?? He is a Veteran with no other health insurance so he has got the run around.. Tests show nothing much, MRI did show some bone problem but he has never injured the foot.. Now he cannot use it at all.
