When is neck pain serious?

Most neck pain is not serious

The NHS describes neck pain as a common problem that generally is nothing to worry about, and says most neck pain only lasts a few weeks. Mayo Clinic agrees that most of the time neck pain is not a sign of a serious medical condition, but adds that it can sometimes point to a bigger issue. The aim of this page is to explain which signs the sources treat as warnings. For the usual causes, see what causes neck pain?

Warning signs after an injury

Injury changes the picture. Mayo Clinic says to get emergency medical care for severe neck pain after an injury, giving a motor vehicle accident, a diving accident and a fall as examples. The NHS whiplash page says some symptoms need urgent medical help when the neck has been injured. It lists:

• severe pain despite taking paracetamol or ibuprofen
• tingling or pins and needles on one or both sides of the body
• problems with walking or sitting upright
• a sudden "electric shock" feeling in the neck and back that may go into the arms and legs
• weakness in the hands, arms or legs

The NHS explains that these symptoms could be caused by damage to the nerves in the neck or back. It advises asking for an urgent GP appointment or getting help from NHS 111, and it says to avoid anything that could be dangerous, such as driving or cycling, until you have spoken to a clinician. More on this injury is on the page about whiplash.

Signs that a nerve may be involved

Pain that spreads is another signal. The NHS lists other symptoms such as pins and needles or a cold arm as reasons to see a GP, noting that they could be something more serious. Mayo Clinic advises contacting a healthcare professional if neck pain spreads into the arms or legs, or comes with numbness, weakness or tingling. A nerve in the neck being squeezed is one possible explanation, covered on the page about a pinched nerve in the neck, although only a clinician can say what is happening in an individual case.

Neck pain with a headache or fever

Mayo Clinic lists a headache that comes with neck pain among the reasons to contact a healthcare professional. The NHS headache advice goes further for severe cases. It says to call 999 or go to A&E if someone has a headache with a very high temperature, a stiff neck, or bright lights bothering them, or a rash that does not fade when a glass is rolled over it. Separately, Mayo Clinic names meningitis among the diseases that can cause neck pain. Whether a neck problem can itself be the source of a headache is a separate question, covered on can a problem in the neck cause headaches?

Pain that does not settle

Duration matters too, but the sources use different time frames. The NHS advises seeing a GP if neck pain or stiffness does not go away after a few weeks, if painkillers have not worked, or if you are worried about the pain. Mayo Clinic advises contacting a healthcare professional if neck pain is very painful or intense or does not get better after a few days. The NHS adds that in many areas people can refer themselves to community musculoskeletal (MSK) services, such as physiotherapy, without a GP referral. The wider neck and headaches section collects related questions.

When to get help

If you have severe neck pain after an injury, weakness, loss of feeling, trouble walking, or a headache with a stiff neck and high temperature, the sources above say to seek urgent or emergency care without waiting. For neck pain that is milder but lasting, spreading, or worrying you, they say to book a routine appointment with a GP or other healthcare professional. Practice varies by country and by clinician, so local emergency numbers and services may differ from the NHS ones named here.
