Hi, I can't tell you exactly what this may be , I allso had a Jones fracture and it took over 7 months to heal. I have had lots of problems with my right foot in particular with two surgeries in less than 7 months and a third, a fusion was scheduled till I had this heart attack thing. Anyway, there is an excellent internet site called. Myfootshop.com where they address nothng but foot problems, foot and ankle surgery, etc. I have posted on there for a longtime till I had this heart thing, and Now I am waiting till I have my foot surgery and I will post there again. There is an excellent dr. there known as Dr. Oster
who can answer your questions as well as feedback from other people going through the same thing. Try giving a post. Sometimes it may take a few days for the dr. to post as he is the ONLY DR. THERE, but he will get back to you, iN the meantime, someone else may know what is going on. Good luck. Flluffypurrcat
What does the doctor think is causing the symptoms? Could it just be that the blood is pooling and then when you stand it disperses? Sorry, my answer is not more medical, but it's the only thing that came to mind.
Is a leg ultrasound similar to a carotid artery U/S? Can the doctor see the actual blood flow?
