Rheumatoid arthritis is an auto-immune condition that affects about 400,000 people in the UK.
It’s caused by the body’s immune system attacking the cells that line joints by mistake.
The condition can make joints become swollen and painful, according to the NHS.
You should see a GP if you’re showing the signs of rheumatoid arthritis, including chest pain.
“As well as problems affecting the joints, some people with rheumatoid arthritis experience a range of more general symptoms,” the NHS said.
“The inflammation associated with rheumatoid arthritis can also sometimes cause problems affecting other areas of the body, such as dry eyes and chest pain.”
Chest pain could be a sign of rheumatoid arthritis, if the heart or lungs are affected.
You should always seek medical help if you suffer from persistent chest pain.
Other signs of rheumatoid arthritis include fatigue, unexplained weight loss and a high fever.
Persistent sweating and having a poor appetite are also symptoms of the condition.
The main signs of the arthritis are joint pain, and stiffness in the joints.
Some patients develop firm swellings under the skin around the affected joints, known as rheumatoid nodules, the NHS added.
There’s currently no cure for rheumatoid arthritis, but some treatments could help to reduce symptoms.
Disease-modifying anti-rheumatoid drugs are particularly effective in easing symptoms.
Some lifestyle changes could also help to reduce joint pain.
Regular exercise and following a healthy, balanced diet are key to reducing the number of flare-ups, the NHS said.
