Fluid retention

Yesterday and today my left leg has swollen up (from mid-calf down to the toes). Its not painful at all, just looks awful - my toes look little sausages lol! Last night I laid with my legs up to see if that would do any good - but to no avail. It went down overnight though, but has returned again this afternoon.

As far as I know I haven't banged it or done anything different and my right leg is absolutely fine.

Might be something to do with the weather, just very strange.

I'm not going to panic and there's no pain which is a good thing - I think its just plain old fluid retention.

Does anyone know of anything I can do to bring the swelling down? I'm at my desk all day so difficult to get my leg higher than my hips (without raising a few eyebrows!)

Thanks girls
