5 Possible Blue Legs/Feet/Toes Causes

The list below shows results from the use of our quiz by Buoy users who experienced blue legs/feet/toes. This list does not constitute medical advice and may not accurately represent what you have.

Raynaud phenomenon

Raynaud phenomenon, also called Secondary Raynaud syndrome, is a condition that causes small arteries in the skin to abnormally constrict on exposure to cold water or air. This limits blood flow to the hands, fingers, feet, toes, nose, and ears.

Secondary Raynaud syndrome is rare and is caused by another underlying medical condition, often a connective tissue disorder such as rheumatoid arthritis, scleroderma, or lupus.

Women are more likely than men to be affected, especially if living in cold climates. Family history and smoking are also risk factors.

Symptoms include the hands and feet becoming numb and cold. The skin color changes from pale to bluish, and then to red as the skin warms again.

If not treated, patients may get ulcerated sores or deformities of the fingers and toes, or even gangrene, due to the lack of circulation.

Diagnosis is made through patient history, physical examination, and blood tests.

Treatment includes medications to help increase circulation; treatment of any underlying conditions; and lifestyle changes to gain better protection for the extremities in cold conditions.

Rarity: Common

Top Symptoms: distal numbness, cold toe, cold fingers, spontaneous toe pain, spontaneous finger pain

Treatments focus on addressing your unique case and need for support. They include a combination of symptomatic therapies, physical therapy, speech therapy, possible surgery, and treatment of underlying and associated conditions.
