I have varicose veins (legs and vulval). I've seen people on the Midwives programme wearing compression socks during labour. Is this to protect their veins? I thought socks weren't suitable for varicose veins in pregnancy as they are too tight at the top but don't think tights would be very practical in labour 
.
I'd rather wear neither as neither are comfortable but are they recommended? I am wearing the tights in pregnancy when I could be bothered to.
