What to do if…
you notice purple spots or bruising that appear suddenly without injury

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy UK guide

Short answer

If purple spots or a rash do not fade when pressed and you feel very unwell, have a fever, stiff neck, confusion, breathing difficulty, faintness, or you are worried it could be serious, call 999 or go to A&E now. If you are otherwise well but the spots or bruising appeared suddenly without injury, get same-day medical advice.

Do not do these things

  • Do not wait to see if it spreads if you feel unwell, have a fever, or the rash does not fade when pressed.
  • Do not rely on a home check to rule out something serious; if you are unsure, get urgent advice.
  • Do not stop blood thinners, steroids, chemotherapy medicines, prescribed aspirin, or any other prescribed medicine unless a clinician tells you to.
  • Do not keep pressing or rubbing the spots to check them again and again; check once, then seek help if concerned.
  • Do not drive yourself to A&E if you feel faint, confused, very weak, breathless, or severely unwell.

What to do now

  1. Do one quick pressure check so you can describe what you see. Press the spot or rash firmly for a few seconds. Some people use the side of a clear glass. If it does not fade, or you cannot tell, describe it as a rash or spots that do not fade when pressed. On brown or black skin, also check paler areas such as the palms, soles, roof of the mouth, whites of the eyes, or inside the eyelids.

  2. If the rash does not fade and you feel very unwell, get emergency help now. Call 999 or go to A&E. Say: “New purple spots or rash that does not fade when pressed.” If you can, ask someone else to drive you; if you feel very unwell, ask for an ambulance.

  3. If the spots do not fade but you do not feel very unwell, get urgent same-day advice. Contact NHS 111, or your local urgent care or GP out-of-hours service if 111 is not your local route. Say: “Sudden purple spots or bruising without injury, and the spots do not fade when pressed.”

  4. If the bruising or spots fade when pressed but appeared suddenly without injury, still seek same-day advice. Contact NHS 111, your GP, or an urgent care service today, especially if there are many spots, the bruising is spreading, or this is unusual for you.

  5. Say straight away if you take medicines that can affect bleeding or immunity. Tell the clinician or call handler if you take warfarin, apixaban, rivaroxaban, dabigatran, edoxaban, clopidogrel, prescribed aspirin, steroids, chemotherapy, or any medicine that was started or changed recently. Keep taking prescribed medicines unless a clinician tells you otherwise.

  6. Do a fast check for other warning signs and write them down. Note any fever, shivering, severe headache, stiff neck, dislike of bright light, confusion, fainting, breathlessness, unusual sleepiness, nosebleeds, bleeding gums, unusually heavy periods, blood in urine or stool, black stools, or vomiting blood.

  7. Make it easier to explain without repeatedly checking your skin. Take 2 or 3 photos in good light, include a coin or ruler for scale if you can, and note when you first saw the spots or bruising, where they are, and whether they are spreading. Bring your medicines or a medication list if you go for help.

What can wait

  • You do not need to work out the cause right now; different conditions can look similar at the start.
  • You do not need to decide about tests, referrals, or treatment plans before you have been assessed.
  • You do not need to search for every possible diagnosis.
  • You do not need to change or stop prescribed medicines on your own.

Important reassurance

It is understandable to feel alarmed when purple spots or bruising appear without an obvious injury. Many causes are not life-threatening, but sudden unexplained bruising or a rash that does not fade can sometimes need urgent assessment, so getting advice today is a sensible safety step.

Scope note

These are first steps only, to help you reach the right level of care and avoid unsafe delays. Later decisions may need help from a qualified medical professional.

Important note

This is general information, not medical, legal, financial, therapeutic, or other professional advice. It cannot diagnose the cause of purple spots or bruising; if you feel very unwell, or you are worried something is seriously wrong, seek urgent medical help.
