What are the signs of arthritis in your feet? I have had real bad swelling now for the past 4 months, more so in my right foot . My doctor had me take an ultra sound to make sure I don t have a blood clot & I didn t. He had an x-ray taken to make sure I hadn t broken or fractured anything in my feet & I hadn t. He checked my blood pressure and that was low, 117/49. So how can I know if this is arthiritis in my feet. (I have bad inflamation, puffiness on top and around ankles; also light pain across my toe joints)
