You need to see a doctor and I would do that ASAP.  This could be serious.

If on your legs, it's more than likely varicose veins. They can be painful. 

Varicose veins are swollen, twisted, and sometimes painful veins that have filled with an abnormal collection of blood.

Treatment

Treatment is usually conservative. You will be asked to avoid excessive standing, raise your legs when resting or sleeping, and wear elastic support hose.

You may need surgery or nonsurgical treatment for:

• 
  

  Leg pain, often described as heavy or tired

  
  


• 
  

  Skin ulcers or sores that are caused by poor blood flow through the veins

  
  


• 
  

  Improving the appearance of the legs

  
  


• 
  

  Lipodermatosclerosis - fatty tissue under that skin that hardens over time, caused by high blood pressure in a vein

  
  

Vein stripping is surgery to remove varicose veins in the legs. It is usually reserved for patients who are having a lot of pain or who have skin ulcers.

Noninvasive treatments for varicose veins do not involve surgery. Examples are:

• 
  

  Sclerotherapy

  
  


• 
  

  Laser ablation

  
  


• 
  

  Radiofrequency ablation
