Arthritis: Three unrelated ailments that could trigger 'extremely painful joints'

Considerably shorter in duration than other types of arthritis, Reiter’s syndrome can last for around three months to a year. However, for some people, “random” flare-ups can become commonplace for years to follow. Typically triggered by some sort of infection elsewhere in the body, the arthritic pain tends to be felt in the knees or ankles. One ailment that could trigger an episode of reactive arthritis is a “tummy bug”.

If you’re experiencing a stomach bug, the national health body recommend drinking plenty of fluids, washing your hands often (so not to spread the viral infection), and to try peppermint tea to help ease wind and bloating.

Another possible culprit of reactive arthritis is a throat infection.
