I don’t see how you can tolerate that level of pain. It’s the worse I’ve ever experienced. I am now incapacitated, on the sofa worried about a pulmonary embolism while awaiting an appointment at vascular clinic tomorrow. My heroic wife is pushing me around on a wheeled mechanic’s stool until we get a wheelchair, too, tomorrow. I can only walk ~10’ on affected left leg, then must sit and regain equanimity. I wish I knew the specific causation… .
