What to do if…
your lips or fingertips look bluish and you feel unwell

Short answer

If your lips, tongue, face, or skin look blue or grey and you feel unwell, call 999 for an ambulance now. If it’s only fingers/toes that look bluish, you still need urgent help if you feel unwell or have warning symptoms.

Do not do these things

  • Do not “wait to see if it passes” if the blueness is new, spreading, or you feel worse.
  • Do not drive yourself to A&E if you feel faint, breathless, confused, or your lips/face look blue/grey.
  • Do not lie flat if you’re struggling to breathe (unless you’ve fainted and someone is helping you safely).
  • Do not take someone else’s medication (including leftover antibiotics, sedatives, or strong pain medicines).
  • Do not keep yourself in the cold “to test if it’s circulation” if you’re already unwell.

What to do now

  1. Decide the emergency route (don’t overthink it).
    • Call 999 now if you have blue/grey lips, tongue, face or skin, or you have any of these: difficulty breathing, chest pain, confusion, unusual drowsiness, dizziness, collapse, or you’re getting worse.
    • If it’s only fingers/toes that look bluish and you’re otherwise stable, warm up gently (see step 5) and call NHS 111 for urgent advice—but call 999 if you feel unwell or develop any warning symptoms.
  2. While help is being arranged, get into the best position for breathing. Sit upright, slightly leaning forward, shoulders relaxed. Loosen tight clothing around the neck/chest.
  3. Tell the call handler the key details. Say: “My lips/fingertips look bluish and I feel unwell. I’m worried about oxygen/breathing/circulation.” Mention any chest pain, breathing difficulty, confusion/drowsiness, dizziness, or collapse.
  4. Use only your own prescribed rescue treatment if you have one.
    • If you have asthma/COPD and a prescribed reliever inhaler for sudden breathlessness, use it as directed on your plan/label while waiting.
    • If you have home oxygen prescribed, use it exactly as prescribed.
  5. If it’s mainly hands/fingers and you’re cold, warm gently (only if it doesn’t delay urgent help). Move to a warm room, use a blanket, and warm hands gradually. Do not delay calling 999 if you’re unwell or have warning symptoms, or if lips/face are blue/grey.
  6. Make it easy for responders. Unlock the door if you can, turn on a light, secure pets, and have your medication list (or boxes) and key conditions ready.

What can wait

  • You do not need to figure out the cause right now.
  • You do not need to decide “GP vs A&E” first if you’re unwell with blue/grey lips/face—start with 999.
  • You do not need to tidy up, shower, or “look presentable”.
  • Work messages, travel plans, and explanations can wait.

Important reassurance

It’s understandable to feel frightened by this. Blue/grey colouring plus feeling unwell is a sign to get urgent medical help—calling 999 is a protective step, not an overreaction.

Scope note

This is first-steps only to keep you safe and get timely assessment. The right next decisions depend on what’s causing the low oxygen/circulation problem, which needs professional evaluation.

Important note

This guide is general information, not a diagnosis. If you think you or someone else is seriously unwell—especially with blue/grey lips or breathing difficulty—seek emergency help immediately.
