Vitamodo School · Bundle 3: Sleep as Symptom · Brochure 10 of 10 · Version 1.0
Andris Saulitis, MD
For those who: live with persistent pain that has been treated for years, alongside a sleep complaint that has been treated for years, and have begun to suspect the two are one situation.
Not for those who: have a new severe pain that has not been medically evaluated. The brochure assumes a known chronic condition; new severe pain belongs in clinical assessment first.
What this is — the clinical reality
Chronic pain and sleep are not two separate problems. They are a single self-sustaining loop. The pain disrupts the sleep; the disrupted sleep lowers the pain threshold and increases the perception of pain the following day; the now-amplified pain disrupts the next night's sleep more severely. The person carrying both arrives in clinical care with two complaints that have been treated by two separate specialties, with two separate medication regimens, neither of which fully resolves either complaint — because the underlying pattern is one loop, not two diseases.
This brochure is for people who live with persistent pain — back pain, joint pain, fibromyalgia, neuropathic pain, post-surgical pain, migraine, gut pain, pain of any chronic medical condition — and whose sleep has been damaged by it, by the medications used to treat it, or by the secondary mood and life changes the pain has produced.
Three systems carry the change.
The first system is the mechanical and positional load on sleep. Pain that worsens with pressure, with stillness, with certain positions, or with the small movements of normal sleep will produce micro-arousals through the night. The person may not remember waking, but the sleep architecture shows the disruption: less deep sleep, fragmented REM, the dawn rise occurring in a body that has not finished the night's repair work. Different pain patterns interact differently with the bed — fibromyalgia is often worse with stillness, back pain worse with certain positions, neuropathic pain worse with light touch — but the result is similar: the bed is no longer a place of rest, and the body has lost the architecture sleep requires.
The second system is the pharmacology of pain medications. Opioid analgesics, even at modest doses, fragment sleep substantially — they reduce slow-wave sleep, suppress REM, and produce micro-withdrawal arousals as the dose wears off through the night. Gabapentinoids (gabapentin, pregabalin) are sometimes more sleep-friendly but produce tolerance and a withdrawal cycle of their own. Non-steroidal anti-inflammatories taken in the evening can disrupt sleep in some patients. The pharmacology being used to treat the pain often becomes part of the sleep complaint, and the person has rarely been told this directly. The exception that is frequently missed: tricyclic antidepressants at low doses, given specifically for neuropathic pain and chronic pain syndromes, often improve both pain and sleep — but their selection requires specialist input.
