Varicose veins are caused due to excessive pressure brought to bear on the legs or the abdomen. These are brought on by advancing age, obesity, pregnancy, hormonal changes and a host of other factors, which may include genetic or epigenetic factors as varicose veins often run in families.
Symptoms include veins that look dark blue or purplish red, swollen, and twisted under the skin. Some people do not have any symptoms. Mild symptoms may include: heaviness, burning, aching, tiredness, or pain in the legs. Symptoms may be worse after long periods of immobility and include swelling of the feet and ankles and itching directly over the vein.
