My mother has a serious issue with her right leg, and it causes her pain. In addition, her right foot swells occasionally. I have taken her to her primary care physician, and to the vascular surgeon he recommended. Neither one of them can identify the problem. I even took her to a podiatrist, although I was certain he could not help! I was correct! I don't know what physician to try next, and I'm very concerned that she might have a blood clot. The vascular doctor did an ultrasound and found nothing. Has anyone been faced with a similar problem, and if so, what type of physician should I try next??
