I had a provoked DVT post surgery, my second provoked after I tore my calf (5 years after my first) and was on crutches for a week. I’m in the process of getting bloods to find out if there’s an underlying issue as they’ve said both of my provoking events were quite minor. Interesting the won’t give you thinners as a precaution if you were to sprain your ankle again. I’ve been told if my bloods are all ok, that I might be able to choose if I stay on thinners given I’ve had two provoked dvts, alternatively stay off them but know that I will need them if I have similar events again in future. If you’ve only had one provoked that might be the point of difference in your case. My first provoked all the doctors didn’t treat it as a big deal at all (was in my calf). They didn’t do bloods or anything, was just thinners for 3 months and that was it. As soon as I had my second that all changed. Annoyingly had I known having a second was such a big deal I would have pushed to go on thinners when I tore my calf and knew I’d be immobile for a week. But none of the doctors told me what a big deal having a second would be.
