#AUTOIMMUNE PHENOMENA SYMPTOMS SKIN#

It’s often so mild that the person never seeks medical attention. Primary Raynaud’s phenomenon is referred to as ‘idiopathic’ because there is no clear underlying cause. If you have a family member with primary Raynaud’s, you’re more at risk of developing it. It affects more women than men, generally under the age of 30. Primary Raynaud’s phenomenon (or Raynaud’s disease, or just Raynaud’s) is the most common form of Raynaud’s phenomenon. Circulation to the rest of the body is generally unaffected.

#AUTOIMMUNE PHENOMENA SYMPTOMS SKIN#

When blood flow returns, the skin turns from blue to red and finally back to its usual colour. When this happens, you may experience stinging pain, tingling and numbness in your fingers or toes. Blood vessels in your extremities narrow, starving the tissues of blood and causing the characteristic blue or white colour change. With Raynaud’s phenomenon, this reaction is exaggerated. Your body protects your internal organs (your core) from heat loss in cold weather by redirecting the blood away from the extremities such as the fingers and toes. However, it can be a symptom of a more serious underlying illness, so it’s important to see your doctor if you experience it. Raynaud’s phenomenon doesn’t usually cause permanent damage.

It can last from just a few minutes to many hours. Raynaud’s phenomenon can occur on its own (primary Raynaud’s phenomenon), or it can be linked to another disease or condition (secondary Raynaud’s phenomenon). It can happen in cold temperatures or when you’re in an emotionally stressful situation. In general, fingers and toes are affected, but other parts of your body such as your nose, lips and ears can be affected too. Raynaud’s phenomenon is a condition that can cause discomfort as the blood supply to your extremities becomes reduced.
