Symptoms of Raynaud's Disease and Phenomenon

An attack of Raynaud's may last a few minutes to a few hours. During an attack, symptoms may include:

• Skin discoloration–during an attack, skin color may change to white, blue, and red.
  • White occurs when the arteries narrow or collapse.
  • Blue appears when the fingers, toes, or other areas are not getting enough oxygen-rich blood.
  • The skin turns red and may become swollen when the attack subsides and blood returns.
• Throbbing and tingling sensations, stinging, pain, swelling of the affected area. This may occur at the end of the attack as blood flow increases and returns to the extremities.

People with secondary Raynaud's may experience other medical problems related to Raynaud's, such as:

• Skin thinning and ulcerations
• Gangrene (tissue death)
• Many other symptoms related to their underlying connective tissue disorder
