Cause #3: Reactive Hyperemia
Reactive hyperemia is the temporary blood flow increase after a brief episode. During ischemia, the body part has a buildup of metabolic waste and oxygen shortage.
Reactive hyperemia is a common consequence of Raynaud’s phenomenon where the vasospasm results in ischemia and necrosis of the affected tissue. There is then an increase in blood flow as an attempt to remove waste and clear cell debris. Reactive hyperemia may be accompanied by paresthesia.
