Working as a receptionist in any other industry can get you in the door, but customer service positions also prove you're capable of dealing with the public -- as long as you have good references -- so retail or restaurant work is relevant experience for your resume.
Compression socks for runners are a super strong elastic sock, typically worn up to the knee. They compress veins on the surface of your leg, as well as arteries and muscles, so that blood is circulated through your legs through smaller circulatory channels.
Compression stockings apply pressure to help prevent the blood in the legs from pooling and clotting. They reduce swelling and help relieve discomfort in a leg where a clot has already formed. You can buy compression stockings at your local pharmacy. However, you need a prescription from your GP for some types.
