NHS Symptom Checker

If you’re not sure what condition you have, or how severe it is, you can use the NHS 111 symptom checker. The checker will:

  1. Answer questions about your main symptoms
  2. Help you find when and where to get help
  3. Arrange for you to be contacted by a clinician, if needed
