Went to the hospital for pain my back. I knew what it was before they told me. Blood clots in the lung. This is the 3rd time. They didn't keep me this time, they sent me home with shots to give myself. I've been on blood thinners since the last time 2010. But I kept forgetting to do refill. Then it needed to approved for more refills so that took 2 more days. So I was off of them for 6 days. Geez. I won't ever do that again.
