These are the consequences of Reduced Blood Flow to a Finger

see next page to continue reading 👌If blood flow is blocked for a long time or the underlying disease is severe:
10. Tissue damage (ischemia)
Cells begin to die if they don’t receive enough oxygen.
11. Ulcers or open wounds
Poor circulation can cause painful sores that heal slowly.
12. Infection
Ulcers or cracks can get infected due to slow healing.
13. Tissue death (gangrene)
Extremely rare unless the blockage is severe and prolonged, but it is the most serious form of circulation loss.
⭐ When to Seek Medical Help
You should get medical attention if:
The finger stays white, blue, or numb for more than 15–20 minutes.
You have frequent episodes.
The finger becomes painful, swollen, or develops sores.
The color change is new, sudden, or only in one finger, which could indicate an artery problem.
