Responding to a couple of posts: Low energy and leg cramps are signs of low iron, you might be anemic, ask your doctor to have your iron checked at your next blood test. Also, ask about taking a multi-vitamin, all of the literature about Warfarin mentions not taking vitamins but it’s more about consistency. I’ve been taking a multi-vitamin daily - with my doctor’s permission - and I’ve had very consistent PT’s and INR’s. I’ve been on 7.5 mgs of Warfarin daily for six months and am holding steady. It is very important to take it every day if you do take a vitamin, it’s important to be consistent.
And about the socks, they are called compression stockings and can be prescribed by your doctor, or some are also available at drug stores, ask a pharmacist at the store.
And also about headaches, it helps me if I stay hydrated. When I don’t drink enough water I tend to get headaches.
I’m back to exercising at my pre-pulmonary embolism rate, it took me six months to get there, and I started slow, but my body has gradually responded. I’m 52 and was pretty healthy before I got sick. Just keep at it, you’ll see results (and feel better too!).
