Coffee is tricky. A study has shown that low doses of caffeine – no more than 100 milligrams – can help reduce the perception of pain. Other sources of caffeine you may want to try if you don’t like coffee are tea and chocolate. Caffeine delivers pain relief by exerting so-called ‘peripheral action,’ that is, relief at the site of an injury. In doing so, it acts directly on muscle tissue, relieving pain by repairing tissue damage and reducing inflammation.
