What can I do for Raynaud's Syndrome?

Raynaud's syndrome is characterized by fingertip discoloration (blue or purple) triggered by cold or stress, often lasting minutes to hours. Treatment typically involves avoiding cold exposure and medications affecting the sympathetic nervous system. Risk factors include history of frostbite, female gender (20s-40s), and estrogen dominance. Primary Raynaud's is idiopathic, while secondary forms stem from connective tissue disorders. Management includes vitamin B1 supplementation and inositol hexanicotinate to support symptom relief and autonomic nervous system function.
