Yes. They have done a dopplers on my feet. I have also had ultrasound from the groin to the foot. My feet are not swelling anymore since I have been treating for the diabetes. We believe it went undiagnosed for some time. My blood sugar levels were off the charts high and we are bringing them down slowly but not without their fun side effects. I am hoping the Xarelto will help in healing with both the LV and Diabetes. I don't believe the two are linked though. I just have the luck of bad genes in the family with Diabetes. It gets frustrating when I get treated and diagnosed with something it is lifelong.... Just once it would be nice to go the doctor and it be one and done. I know we all live with this disease and it definitely has its lows. I can't believe I didn't look for a support group before now. It just feels good to be able to share experiences and lift each other up in ways that probably nobody else can.
