What Is Raynaud’s Disease?
Raynaud’s disease is a condition characterized by a decrease in blood flow to the fingers. Sometimes, it would also lead to less blood flow to other body parts, such as the nose, knees, nipples, toes, or ears. This occurs due to blood vessel spasms in these regions, which can be a result of emotional upset, stress, or cold weather. Raynaud’s can be in the primary form or secondary form. This disease is mostly associated with connective tissue or autoimmune problems like scleroderma, lupus, Buerger disease, CREST syndrome, rheumatoid arthritis, polymyositis, thyroid disorders, pulmonary hypertension, or blood disorders.
