|If I just never wake up, I'll never feel the pain.|
The short answer is yes. It's been well-documented that poor sleep and increased pain have a strong correlation. Testing responses to specific stimuli before and after sleep deprivation in subjects has definitely shown an increased output of pain to all types of different pain sources. Heat, cold, pinprick, deep pressure, and other types of provocations all show these results.
However, when looking at sleep deprivation and the cascade of other symptoms it provides, it brings up another questions. Could these related conditions be the true cause for pain sensitivity? Indeed, some studies are finding that sleep disturbances are do have a more indirect link to pain, suggesting that increased pain perception is more-related to those depressive symptoms and how much attention to pain that these individuals may have.
So, perhaps we're looking at is a type of central nervous system fatigue. As I've discussed before, both physical and mental illnesses can propagate these chemical changes in the brain and contribute to pain.
No matter the cause, it's clear that poor sleep and pain ARE related, and unfortunately, this relationship is cyclical. Poor sleep heightens pain levels, and it doesn't take much thought to understand that chronic pain results in even more sleep disturbances.
Treating this, obviously, is a complex thing, and could very well require a comprehensive medical team, rather than one therapist, including sleep specialists, psychologists, and more. On my own, as an Athletic Therapist, what I can do is try to begin breaking that pain-sleep cycle, just like the pain-spasm cycle, and provide a bit of relief at a time in order to slowly improve sleep quality as the client and I go.
Sleep on that.
