the blood clots

I've been active like I'm just about back to normal. When sitting, I try to keep my leg up horizontal. It's rough on my butt, though. For some reason, that posture puts my butt to sleep. Probably not a good idea to constrict blood flow right there at the top of the leg. I'm not sure how important it is to keep the leg raised at this point. Does elevating it help the blood flow and help the clots to dissolve, or does it just reduce discomfort? I know there are still clots since the leg doesn't feel back to normal. And I'm supposed to stay active. Is sitting all day at work keeping the clots from dissolving completely? Or do they just normally take this long to go away? And if the former, how am I supposed to deal with this for the rest of my life?

A friend said I should try to avoid the cold. He says "pay someone to shovel for you." As if there was anyone around to do that (besides the neighbor who already brings his snowblower all the way around to our driveway when we get more than a couple of inches of snow). So I was out shoveling for twenty minutes tonight. But his comment about the cold had me thinking. There are things that are not causes of the clots, but that can be exacerbating conditions. I think dehydration is one of them. Maybe cold is another. And I'm cold all the time. I've been wearing my coat at work lately. My outdoor winter coat. It's supposedly 72°, but my body heat doesn't get replenished when I'm inactive, and the cold sinks to the bones.
