Varicose veins during pregnancy

Has anyone been put off work due to pain from varicose/spider veins during pregnancy? I had them with my second pregnancy and they were very painful as I have to stand most of the day at work.. I read with each pregnancy they get worse and this time they are already worse than before & I’m only 21 weeks. My dr wrote a prescription for compression tights but has anyone been put off of work because of the pain? It’s pretty unbearable at times and I have them in my vulva and all over my legs.
