If you have a vascular disorder, it means you have a problem with arteries and veins. Arteries are pipes that bring blood from the heart to the fingers. Veins are pipes that return the used blood back to the heart and lungs. There can be many different causes of vascular problems. Here are five common causes:
- Traumatic injury
- Flattening of pipes
- Blocked pipes
- Tumors or deformed, tangled pipes, which may or may not be present at birth
- Vessel spasms
Some signs of vascular problems include pain, color changes in the fingertips, wounds that won’t heal, numb hands and swelling.
