Chronic pain can change the shape of a day. Sleep loss can do the same. When both are present, the effects often overlap: a night spent shifting for comfort can make the next day feel harder, and a painful day can make bedtime feel like another challenge to get through.
At our Fort Lauderdale practice, One Mind provides physician-led care for people living with persistent pain and complex health concerns. We believe a useful pain evaluation should make room for sleep, mood, activity, medications, previous treatment, and the specific pattern of symptoms you are carrying.
Poor sleep does not have one meaning, and chronic pain does not have one cause. Still, the relationship between them is important to discuss. It can influence how you feel, function, and make decisions about care.
Why Pain Can Keep You Awake
Pain may make it difficult to fall asleep, stay asleep, or return to sleep after waking. Some people feel worse when they lie still. Others wake repeatedly because of discomfort, muscle tension, numbness, burning, or a need to change position.
The problem is not always pain intensity alone. Worry about another difficult night can become part of the bedtime routine. You may start watching the clock, calculating how little sleep remains, or avoiding bed because you expect discomfort. This is exhausting. It can also make sleep feel less restorative even when you have been in bed for several hours.
Research has consistently found that sleep disturbances are common among adults living with chronic pain. A meta-analysis of sleep disturbances in chronic pain described a substantial burden of insomnia symptoms and sleep disorders in this population (Mathias et al., 2018). Earlier work has also described an ongoing relationship between sleep disturbance and widespread pain (McBeth et al., 2015).
Why Poor Sleep Can Make Pain Feel Harder
A poor night of sleep does not mean you have done anything wrong. It may, however, change the way the body and brain process discomfort the following day. You may notice lower patience, less energy for movement or daily tasks, and a shorter distance between a painful sensation and feeling overwhelmed by it.
This is not simply a matter of willpower. Sleep supports attention, emotional regulation, and physical recovery. When sleep is repeatedly disrupted, the nervous system may have fewer opportunities to settle. A recent review of why sleep matters across the lifespan for chronic pain describes the relationship as bidirectional, with pain affecting sleep and sleep disruption influencing pain experience (Kelleher et al., 2026).
For some people, this creates a difficult loop. Pain interrupts sleep. Fatigue makes the next day less manageable. Reduced activity, stress, and distress may then make another night of sleep more difficult. Research examining chronic pain has also identified associations between sleep-wake disturbance and physical activity that are worth considering in the context of each person’s daily routine and abilities (Varkey et al., 2026).
Mood, Stress, and the Pain-Sleep Cycle
Pain and poor sleep can affect mood, while anxiety and depression can make pain and sleep concerns feel even more complicated. That does not mean every person with insomnia has a mood disorder, or that pain is psychological. It means the full picture matters.
If anxiety is part of what keeps your mind active at night, it may be worth discussing alongside physical symptoms. Ketamine may be discussed as an off-label psychiatric treatment when clinically appropriate, and anxiety treatment considerations should be individualized and grounded in a careful review of your history.
Similarly, low mood can affect motivation, sleep patterns, appetite, concentration, and the ability to maintain routines that once felt ordinary. A 2025 study found that poor sleep quality and mood symptoms may increase chronic pain risk among people with insomnia (Liu et al., 2025). This does not establish a single cause for any individual. It does support asking thoughtful questions about both sleep and emotional well-being.
When depression is present, ketamine may also be considered off-label for psychiatric care in appropriate circumstances. Any conversation about care for depression should be coordinated with the rest of your medical and mental health care.
Sleep Problems Are Not All the Same
“Poor sleep” can describe many experiences. You may have trouble falling asleep. You may wake early and be unable to return to sleep. You may sleep for many hours but wake unrefreshed. You may also snore loudly, gasp, have restless legs, or feel excessively sleepy during the day.
Those details matter. Sleep apnea, medication effects, caffeine, alcohol, trauma-related nightmares, hormonal changes, and irregular schedules can all influence sleep. A recent systematic review emphasized the importance of identifying obstructive sleep apnea in chronic musculoskeletal pain rather than assuming every sleep complaint is explained by pain alone (Perea et al., 2025).
PTSD can also involve nightmares, hypervigilance, and disrupted sleep. Ketamine may be discussed as an off-label psychiatric treatment for PTSD when clinically appropriate. For patients managing trauma-related symptoms, PTSD treatment options may be part of a broader conversation with qualified clinicians.
What to Bring Up During a Pain Evaluation
A productive evaluation begins with specifics. Rather than saying only that you sleep badly, consider describing what happens before, during, and after the night.
You may want to discuss:
- When pain is most disruptive, including whether it changes with position or movement
- Whether you struggle to fall asleep, stay asleep, or wake too early
- Snoring, gasping, nightmares, restless legs, or daytime sleepiness
- Medication timing, including over-the-counter sleep aids and pain medications
- Changes in mood, stress, activity level, work, or family responsibilities
- What has helped, what has not helped, and what side effects you have experienced
For people with certain pain conditions, such as CRPS, symptom patterns and prior care can be especially important to review. Ketamine for pain conditions such as CRPS is an off-label use. Our CRPS care begins with an individualized discussion of symptoms, medical history, and treatment considerations.
How We Approach Pain Care
We do not reduce persistent pain to a single score or a single solution. Our physicians review your medical history, current symptoms, medications, prior treatments, and relevant mental health concerns. We also want to understand what pain and poor sleep are taking away from your daily life.
We offer regenerative medicine for pain after an individualized assessment. This service is not presented as a treatment for sleep problems, and it is not a substitute for evaluating potential sleep disorders or other contributors to fatigue. The appropriate next step depends on your diagnosis, health history, goals, and the care you may already be receiving.
Sometimes the most useful outcome of an evaluation is a clearer set of questions. Is there a sleep disorder that needs attention? Could medication timing be affecting sleep? Are stress, depression, or trauma symptoms adding to the burden? Would communication with your primary care clinician, pain specialist, therapist, or sleep clinician help create a more coordinated plan?
When the Cycle Feels Too Heavy
Chronic pain and sleep loss can be isolating. If you are feeling hopeless, unsafe, or are having thoughts of harming yourself, call or text the 988 Suicide and Crisis Lifeline at 988 for immediate, confidential support. In an emergency, call 911 or go to the nearest emergency department.
You do not need to solve the pain-sleep cycle in one conversation. But naming it is a meaningful start. At One Mind, we can help you prepare for a thoughtful discussion of persistent pain, sleep disruption, and the factors that may be making each one harder to manage.
Frequently Asked Questions
Can poor sleep cause chronic pain?
Poor sleep is not the sole cause of chronic pain. However, ongoing sleep disruption may influence pain sensitivity and daily coping, while pain itself can interfere with sleep. The relationship is often two-way and deserves individual evaluation.
Should I ask about a sleep study if I have chronic pain?
It may be appropriate to ask, especially if you snore, gasp during sleep, wake unrefreshed, or experience significant daytime sleepiness. Your primary care clinician or a sleep specialist can help determine whether further evaluation is warranted.
Can pain treatment also fix my sleep?
Not necessarily. Sleep problems can have multiple contributors, including pain, medications, stress, mood symptoms, and sleep disorders. We encourage a care plan that considers both pain and sleep rather than assuming one intervention will address everything.
What if my pain is affecting my mental health?
That is important to say aloud during your evaluation. Persistent pain can place real pressure on mood, relationships, work, and daily functioning. Coordinated support may include medical, behavioral health, and sleep-focused care depending on your needs.
