Raynaud's Disease
Left hand numbness may occur with Raynaud's disease, a disorder in which blood vessels in the fingers and toes constrict when exposed to the cold or when a person is experiencing stress. The fingers or toes turn white or bluish. When they warm up or the stress is alleviated, the blood flow normalizes, and numbness and tingling may develop.
Injuries, medications and other diseases may also trigger Raynaud's disease. Management includes avoiding triggers and keeping fingers and toes warm.8‘Raynaud’s Disease.’ MedlinePlus, U.S. National Library of Medicine, 9 June 2020, medlineplus.gov/raynaudsdisease.html
