My mom had a clot in head for two years. She has been on different types of medicine including blood thinners. Lately she had been complaining about severe pain in her legs. The doc ordered MRI and XRays and stuff. The results are not in yet but doc thinks it is less blood circulation to legs! My question is what is the reason for having low blood circulation to legs and can it be cured? Thanks PS: My mom lives in India.
