I have had swelling in my feet, ankles and legs. My feet and ankles also have discoloration and are painful. Feels like pins are sticking in them at times. I am trying to determine what type of doctor I should see because I am due to go into have back surgery in a few days and I want to ensure that there is no serious issues. My swelling has been an issue for the past few months and my primary care doctor doesn t know what the problem is.
