How To Cure Sore Foot And Swelling In Ankle Due To Bilateral Lung Clots?

I have had a sore foot and swelling in my ankle and foot. Slight bruising of the bottom of my foot but the pain seems to be working its way up my leg from when it first started. I was sitting in a chair and I could hardly move my ankle when I got up. I have been wearing pressure stockings and I am on warfarin from bilateral lung clots when I had a minor surgery in august. I have had a hard time walking on it since Friday and it seems to be getting worse. I wore a orthopedic boot for a day that I had previously and it seemed to help. It feels like I am walking on a piece of wood in the arch of the bottom of my foot. I do not recall hitting anything or doing anything that would cause a break. I had a unusually high blood pressure 190/90, 184/86 on the right side and a bit better, 164/84 on the left side after two high readings on the right she took it on my left side which was very high as it is usually around 130-140/70-80. Should I just wait till I wake up or go in right away? I can not afford to pay for any answer but if you can give me some direction I would appreciate it. Thanks, Jamie
