Trauma or Injury
Trauma or injury to the legs can cause superficial and deep vein damage, leading to spider veins. You should treat wounds immediately to prevent further damage. Long-term effects of trauma or injury range from chronic swelling, persistent spider veins, bruising, and pain to more serious conditions such as blood clots, nerve damage, or ulcers.
In terms of chronic venous insufficiency or chronic venous incompetence, trauma or injuries to the muscles or connective tissue in the arms or legs can result in poor circulation in that area which causes low blood pressure and eventually spider vein symptoms. An example of this would be if someone tore their hamstring while playing sports when they were younger and didn’t get it treated properly, preventing them from getting sufficient exercise later in life to keep their veins healthy.
