[35F] Experiencing cold extremities and leg discoloration

What might be happening

Based on the information provided, possible diagnoses include:

• Raynaud's Phenomenon: This condition causes some areas of your body — such as your fingers and toes — to feel numb and cold in response to cold temperatures or stress. It can also cause changes in skin color, from white to blue to red. Raynaud's is more common in women and in people living in colder climates.

  • Treatment typically involves lifestyle changes to reduce exposure to cold temperatures and stress. Medications can be prescribed to help control symptoms.

• Autoimmune conditions: Given your positive ANA (Antinuclear Antibody) test and history of Hashimoto's disease (an autoimmune condition), it's possible that another autoimmune condition could be causing your symptoms. Autoimmune conditions can cause a wide range of symptoms, including changes in skin color and temperature sensations.

  • Treatment typically involves managing symptoms and may include medications to control the immune response.

• Peripheral artery disease (PAD): This condition results from a buildup of plaques in your arteries that reduce blood flow to your limbs, causing them to feel cold. PAD is more common in people over 50 and in people with hypertension, which you have.

  • Treatment typically involves lifestyle changes, medications, and sometimes procedures to open blocked arteries.

What you can do

1. Keep a symptom diary: Note when your symptoms occur, what you're doing when they occur, and how long they last. This can help your doctor diagnose your condition.
2. Stay warm: If cold temperatures trigger your symptoms, try to stay as warm as possible. Wear warm gloves and socks, and try to avoid sudden changes in temperature.
3. Exercise: Regular physical activity can increase blood flow and help manage symptoms of Raynaud's and PAD.

What you should look out for

Reasons to see a doctor more urgently:

• If your symptoms worsen or you develop new symptoms
• If you notice sores or ulcers on your feet or legs
• If you experience severe pain in your legs or feet
