"Varicose" is a word that describes a condition in which your veins (the blood vessels in your body that carry blood back to your heart) become swollen and twisted. This can happen mostly in your legs, but it can occur in other parts of your body as well. It can cause pain, discomfort, and other health problems. You might use this word when talking to a doctor or a friend about health issues you're experiencing.
