Should I use this page, or skip it?
Use this page if you have joint pain, stiffness or swelling and need to know which type of arthritis is likely, and whether to start with a pharmacist, a GP, or urgent care. Skip it and get same-day help if one joint is suddenly hot, red and extremely painful, especially with fever. Skip it and call 999 if you have collapsed, cannot breathe properly, or have a major injury.
This is a decision hub, not a diagnosis. It will not tell you which joints you have damaged. It will help you pick the right next page and the right door into the NHS.
If you already know it is osteoarthritis, go to osteoarthritis. If several small joints are swollen with long morning stiffness, go to rheumatoid arthritis. If a big toe or another joint is suddenly extremely painful, see gout.
What does arthritis actually mean?
Arthritis means a joint is painful, stiff or swollen. It is not one disease. The NHS uses the word for many conditions that affect joints in different ways. The useful split is mechanical wear-and-repair problems versus inflammatory or crystal problems versus infection.
Osteoarthritis is the most common type in the UK. Cartilage and the whole joint change over time. Pain is often worse with use and eases a little with rest, though stiffness after sitting is common. Inflammatory arthritis, including rheumatoid arthritis, is driven by the immune system. Joints can swell, feel hot, and stay stiff for more than 30 minutes in the morning. Gout is a crystal arthritis, often starting in the big toe. Septic arthritis is infection inside a joint and is an emergency.
You do not need the perfect label before you seek help. You do need to notice the pattern: one joint or many, slow or sudden, with or without fever, and whether morning stiffness lasts minutes or hours.
How do I tell the common types apart?
Match what you notice to the most likely pattern, then confirm with a clinician. Do not self-diagnose a hot joint as “just a flare”.
| What you notice | More likely | First sensible step |
|---|---|---|
| Gradual pain in knees, hips, hands or spine, worse with use | Osteoarthritis | GP if it limits life; pharmacist for short-term pain relief |
| Several joints swollen, long morning stiffness, fatigue | Rheumatoid arthritis or another inflammatory arthritis | GP promptly; early specialist referral matters |
| Sudden extreme pain in one joint, often the big toe | Gout | Same-day advice; do not wait for it to “settle on its own” if you are unwell |
| One joint suddenly hot, red, too painful to move, with fever | Possible septic arthritis (joint infection) | Same-day urgent care or A&E — this is not a routine GP wait |
| Pain after a sprain or overuse, no swelling of many joints | Strain or injury rather than a long-term arthritis | Pharmacist or GP if it is not settling |
Blood tests do not replace this pattern. They can support inflammatory arthritis. They are often normal in osteoarthritis. A single hot joint may need urgent blood tests, imaging or joint fluid tests to exclude infection.
Should I rest, or keep moving?
Keep moving in a paced way unless a clinician has told you to rest a specific injury. Short rest can ease a flare. Days of bed rest usually make stiffness and muscle weakness worse.
The NHS and Versus Arthritis both emphasise activity as treatment, not as a reward for when the joint feels perfect. Strengthening the muscles that support a painful knee or hip often reduces pain over weeks. Swimming, cycling and walking are common starting points. If a movement sharply increases swelling or night pain, scale it back rather than stopping altogether.
Weight management helps osteoarthritis in load-bearing joints because it reduces force through the joint. It is not a moral judgement and it is not the whole treatment. Pain relief, footwear, walking aids and physiotherapy can sit alongside it.
Do not use a hot, red, feverish joint as a reason to “walk it off”. That pattern needs assessment first.
What can I try before a GP appointment?
For short-term pain, a pharmacist can advise on paracetamol or ibuprofen. Ibuprofen can help inflammatory pain but does not suit everyone — stomach ulcers, some asthma, kidney, heart or liver problems, and pregnancy are reasons to check first. Take the lowest dose that works, for the shortest time, with food.
Heat can ease stiffness. Ice can ease a swollen flare. Neither replaces assessment if the joint is hot and you feel unwell.
Write down which joints, when it started, what makes it better or worse, morning stiffness in minutes, and whether you have psoriasis, iritis, bowel disease, recent infection, or a family history of inflammatory arthritis. That list is more useful than a search for a miracle supplement. No vitamin is a proven cure for arthritis.
If you need a fit note for work, say so at the start of the appointment. See our fit-note guide and appointment checklist.
When does arthritis need a GP or urgent care?
See a GP if joint symptoms last more than a few weeks, keep returning, or stop you working, sleeping or walking. See a GP sooner if several joints swell, morning stiffness lasts longer than 30 minutes, or you have unexplained fatigue with joint swelling. Suspected inflammatory arthritis should not be left to “wait and see” for months.
Get same-day urgent help if:
- one joint is suddenly extremely painful, hot and difficult to move
- you also have fever, rigors, or feel very unwell
- you cannot put weight on the joint after a sudden change
- you have a weakened immune system or a joint replacement and a hot joint
Call 999 if you collapse, are confused, or have chest pain or stroke symptoms as well. Joint pain is then not the priority.
A GP may examine you, arrange blood tests or an X-ray, advise pain relief and activity, or refer you to physiotherapy or rheumatology. Early referral for inflammatory arthritis can protect joints. That is the opposite of waiting until damage is visible on an X-ray.
What treatments does the NHS actually use?
Treatment depends on the type. There is no single arthritis tablet.
For osteoarthritis, the usual package is activity, strengthening, weight management where relevant, pain relief, and physiotherapy. Injections or joint replacement are for people whose pain and function stay poor despite that package. See the osteoarthritis page for the detail.
For rheumatoid arthritis, disease-modifying medicines such as methotrexate are used to calm the immune system and prevent joint damage. Painkillers alone are not enough. See rheumatoid arthritis.
For gout, the immediate need is pain control and then, for many people, a plan to lower uric acid so attacks stop. See gout.
Do not start steroids, immune-suppressing drugs, or unregulated “joint injections” from a website. Those decisions belong with a clinician who can monitor you.
Who is this page not for?
This page is not for a child with a limp and fever — that needs urgent paediatric assessment. It is not a substitute for emergency care of a hot joint. It is not a sports-injury protocol after a collision. It will not tell you which brand of supplement to buy.
If your only symptom is tiredness with no joint swelling, start with tiredness and fatigue rather than assuming arthritis. If pain is mainly in the lower back without swollen limb joints, see back pain.
Common questions about arthritis
- What is the difference between osteoarthritis and rheumatoid arthritis?
- Osteoarthritis is the most common type and usually affects weight-bearing or previously injured joints, with pain that is often worse with use. Rheumatoid arthritis is an autoimmune condition that often causes prolonged morning stiffness, swelling in several joints, and fatigue. Blood tests help with inflammatory types but do not diagnose every arthritis.
- Should I rest an arthritic joint?
- Short rest can ease a flare. Long periods of inactivity usually increase stiffness and weakness. Graded movement, strengthening and pacing are the usual NHS approach unless a clinician has told you to rest a specific injury.
- Is there a blood test for arthritis?
- No single blood test diagnoses all arthritis. Tests such as inflammatory markers, rheumatoid factor or anti-CCP can support inflammatory arthritis. Osteoarthritis is often diagnosed from the history and examination, sometimes with an X-ray. A hot single joint may need urgent tests to exclude infection.
- Can I see a pharmacist first?
- Yes for short-term pain relief advice, and to check whether ibuprofen is safe for you. A pharmacist cannot diagnose the type of arthritis or start disease-modifying treatment. See a GP if symptoms persist, several joints are swollen, or you have prolonged morning stiffness.
- Does arthritis only affect older people?
- No. Osteoarthritis becomes more common with age, but inflammatory arthritis, gout and joint infection can occur in younger adults. Persistent joint swelling in a working-age adult still needs assessment, not a wait until retirement.
- Will I need a joint replacement?
- Most people with arthritis never need surgery. Joint replacement is considered when pain and function stay poor despite exercise, weight management where relevant, pain relief and physiotherapy. It is a planned decision, not the first step.
- Is cracking joints a sign of arthritis?
- No. Painless clicking or cracking is common and is not, on its own, arthritis. Pain, swelling, stiffness that lasts, or a joint that will not move properly are the symptoms that matter.
