Blood then backs up in your leg veins and leads to painful swelling. This condition is one of the contributing factors to varicose veins. If you’re getting sock marks regularly, your body might be trying to send you a signal that your veins don’t let blood flow back up to your heart.
2. Dehydration

If your body doesn’t get enough water, it may damage your blood vessels. Damaged veins may begin to create small leaks that allow fluid to build up in the surrounding tissue.

Side effects from medication

Certain medications can also cause lower leg swelling. Some kinds of antidepressants and blood pressure medications may lead to the unpleasant feeling of swollen feet. Certain types of contraception (especially birth control pills that contain estrogen) can change hormone levels in a woman’s body and cause water retention and leg swelling.
4. Lymphedema

This chronic swelling condition occurs when the lymphatic system — a key part of the immune system — isn’t working properly. According to Dr.
Teter, Vascular Surgeon with Hackensack University Medical Center, lymphedema can develop as a side effect of cancer treatment, result from infection or injury, or appear without any clear cause. Excess body weight is also a known risk factor. Lymphedema most often affects an arm or leg, causing swelling, a feeling of heaviness or tightness, limited range of motion, recurring skin infections, and thickening or hardening of the skin, she adds.
