Morning joint stiffness: when is it serious?

If your hands are stiff in the morning and you have to open and close your fists for a few minutes to get them moving, you may have wondered whether this is ordinary stiffness or a sign of disease. This article sets out the criteria that reliable sources give. The final answer comes from a doctor’s examination.

What is morning stiffness?

After a period without movement, such as a night’s sleep or a long time sitting, a joint moves more stiffly. The NHS writes that in rheumatoid arthritis, pain and stiffness are often worse in the morning or after rest. For many people, a little stiffness in the morning is normal. What matters is how long it lasts and what else comes with it.

How long does it last?

Different sources give different numbers, so no single figure is a firm dividing line:

• Osteoarthritis. The NHS says that in osteoarthritis, morning stiffness is either absent or lasts less than 30 minutes.
• Rheumatoid arthritis. NIAMS lists morning stiffness of more than 30 minutes among its signs, and the ACR writes that it lasts more than an hour but improves with movement. The NHS also says it is often longer than in osteoarthritis.
• Polymyalgia rheumatica. The NHS writes that muscle stiffness in the morning lasts more than 45 minutes, is seen mostly after age 65, and is very rare under 50.
• Spondylitis. The NHS says that in this disease, back pain and stiffness are worse in the morning and at night and get better with activity, not with rest.

On its “When to see a rheumatologist” page, the ACR counts morning stiffness of more than 30 minutes among the signs that may call for a referral.

The takeaway: stiffness that lasts a few minutes and goes away with a little movement is usually not a worry; but stiffness that lasts half an hour or more, especially with swelling or pain, is worth telling a doctor about.

What else should you look for?

Stiffness alone is not enough. A doctor will also ask about the following:

• Joint swelling and warmth. For RA, the NHS mentions swelling, warmth and redness of the joint, and sometimes lumps under the skin (nodules).
• Pattern of involvement. The NHS says the small joints of the hands and feet are often affected first, and usually on both sides of the body, though not always.
• Tiredness, mild fever, weight loss or loss of appetite. The NHS lists these among the general symptoms of RA.
• Duration. The ACR writes that symptoms lasting more than six weeks are a sign of persistent inflammation.
• Recurrence. The Arthritis Foundation says to make an appointment if a joint problem lasts three days or more, or comes back several times in a month.

When should you follow up?

Make an appointment if:

• Morning stiffness lasts half an hour or more (ACR and NIAMS).
• You have repeated swelling of the fingers, wrists or feet (ACR).
• Joint symptoms last three days or more, or come back several times in a month (Arthritis Foundation).
• You are over 50 and shoulder and hip stiffness and pain have lasted more than a week (NHS, polymyalgia rheumatica).
• You have had back pain for more than a few months that is worse in the morning and at night and gets better with movement (NHS).

A general practitioner is usually the first step and, if there is suspicion, will refer you to a rheumatologist (ACR).

Urgent: If one joint suddenly becomes hot and painful and you have a fever, or if over age 50 you develop a new headache at the temple with jaw pain, do not wait for an appointment. See the guide “When should I call urgently?”

What to do until the visit

• Write it down: which joints, how many minutes of stiffness, what makes it better or worse, and whether there is swelling or redness. Show this to the doctor at the first visit (see the “Your first visit and what to bring” guide).
• Time the stiffness with a clock: when you wake up in the morning, how many minutes does it take for your joints to “loosen up”?
• Do not start a new medicine or supplement without advice. The NHS says there is no strong evidence that particular diets or supplements affect rheumatoid arthritis.
• For an exercise plan, see the guide “Staying active and caring for your joints”.

A reminder

Morning stiffness is not a diagnosis. Many joint pains, such as osteoarthritis, are common at older ages, and the stiffness in them is short. On the other hand, rheumatoid arthritis can damage joints in the first years (NIAMS), and early diagnosis gives a better chance for treatment (NHS). So if the pattern fits an inflammatory disease, do not be afraid to follow up.
