digital ischemia

Digital ischemia occurs when blood flow to the fingers or toes is reduced or blocked, depriving the tissues of oxygen and nutrients. This can lead to symptoms like pain, coldness, numbness, color changes (pale, blue, or dark), and even tissue damage or gangrene if untreated. It often results from conditions like blood vessel constriction, blood clots, or underlying diseases such as Raynaud’s phenomenon or peripheral artery disease. Prompt recognition and treatment are essential to restore blood flow, prevent tissue loss, and address the underlying cause.
