The skin may become dry and itchy and you may see the onset of skin ulcers.
  
  

Nerve Issues

This condition will manifest itself as a tingling or numbness associated around your appendages. Advanced cases may result in a complete loss of feeling in these appendages. You may also feel a "pins and needles" effect from lack of circulation to those appendages.
