Swollen ankles and feet but only on holiday

[ilovemynails]

We have just returned from Lanzarote and again my feet and ankles have swollen so much my skin is splitting.
This time I didn't have any alcohol. Did lots of walking and I drunk a lot of either water, lemon barley water or apple juice. I put my feet up in the afternoon for an hour and they are back swollen before we go out for dinner.
Go in a size 4 sandal and come back in a size 6.
Yet within a few hours of landing they were back to normal. This has only happened since I started Blood pressure tablets. Which are not very strong.
I have made an appointment with my GP for advice but can't get in for another 3 weeks.
Does anyone else have this problem. What do you do.

Not to the same extent but mine always swell when I'm abroad- never sure why, assume it's time do with flying?

Flying, a lot more walking and normal and the heat

@MousseMoussei wear flight socks on the plane. This time they were swollen before I'd finish unpacking.

I had this only after starting blood pressure tablets - apparently it is a known side-effect, and they can switch you to a different type if you push for it, so see your doctor.
