Thanks for the reply Karen,

No we have not noticed any real skin color changes. At first I used to see an area by her ankle change color from Blue to white at times but it did not stay one color or the other. Then I realized that the uneffected limb also had that shade from time to time. Are the color changes perminent or do that change back to normal from time to time?

Her skin is not sensitive to touch or air. Not yet anyway. It just hurts during the exams when the doc "pokes" her as she calls it (applies pressure to the areas that cause her pain). At first the Doc thought there may have been a slight diff in temp from her uneffected limb but then thought it could be due to the lack or use and circulation in the limb.

Thanks so much again for the response I was worried about the emg. Do you think it will show if their is an entrapment. Do you know what nerves should be tested?
