The primary problem I treat as a Physiotherapist is pain. Despite the link between pain and sleep being extensively studied over the past few decades, I know little about what the research has found. What I've come to understand is that the bidirectional relationship between sleep and medical conditions such as cardiovascular disease also extends to pain disorders. I'm curious about how many people suffer from chronic pain conditions and concurrent sleep disorders? This blog looks more closely at what we currently know from research about sleep and pain.
