Pain in the lower back (or lumbar region) while lying down can make it difficult to get a good night's sleep, and may affect the way the lumbar muscles, ligaments, vertebrae, and nerves work together to provide control and strength for daily movements and activities.
Possible Causes
Night-time back pain isn’t always a sign of a serious health condition, especially if it only happens occasionally or for a short period of time. But when nocturnal back pain is frequent and bothersome, it might be time to get it checked out. Some of the most common reasons for having back pain while lying down include:
- Strain or sprain: As the most common causes of low back pain, lumbar strains and sprains happen when muscles or ligaments are stretched too far.
- Ankylosing spondylitis (AS): This rare form of arthritis characterized by chronic inflammation in the back and neck tends to improve with exercise and worsen at night.
- Degenerative disc disease (DDD): Gradual deterioration of the spinal discs and vertebrae due to aging can lead to painful, restless nights.
- Spine osteoarthritis: Pain from wear and tear on the joints of the spine may intensify at night due to inactivity.
- Sciatica: The vertebrae in the lower back can further irritate the sciatic nerve in certain sleeping positions, leading to radiating pain in the lower body.
- Spinal tumour: Although rare, pain from a tumour or growth on the spine can worsen when lying down due to direct pressure on the area.
Night-time back pain that wakes you up from sleep or prevents you from sleeping is likely a sign that it's time to discuss the issue with your doctor. Remember that along with lower back pain, muscle stiffness and a limited range of motion are also often reported, especially if the cause is a strain or sprain.
It's also helpful to know how pain is commonly categorized:
To get to the bottom of your nocturnal back pain, your doctor will start with a physical exam and review of your medical history to identify or rule out any serious conditions.
Your doctor will be interested in the specifics of your discomfort and will ask you to describe your pain. You should be prepared to give details on when the pain started, what makes it worse or better, its quality and intensity, and whether you've noticed any additional symptoms like numbness or tingling.
Aside from the basic examination, there are some other tests that the doctor could order to help with the diagnosis, including:
- Neurologic tests, or movement screenings, can measure muscle strength to determine if the pain is nerve-related.
- Imaging tests, such as an MRI or CT scan, can help rule out specific causes of pain such as cancer, infection, or fracture.
- Lab tests like a complete blood count may be helpful for concerning symptoms such as a fever, which may suggest a possible infection, or unexplained weight loss, which may suggest cancer or inflammatory arthritis like AS.
Treatment for lower back pain at night can vary depending on the exact diagnosis. In general, for the most common conditions, doctors will usually recommend remedies to alleviate discomfort at bedtime, such as:
- Applying heat or ice
- Taking an over-the-counter pain reliever
- Gentle stretching or light (not vigorous) exercise
- Physical therapy to strengthen core muscle groups that support the low back
- Spinal injections such as corticosteroid or epidural
Complementary at-home remedies may also be incorporated into your treatment plan. These include:
- Massage therapy
- Acupuncture
- Chiropractic care
When the pain is severe and cannot be relieved with non-invasive methods, it's possible that your doctor may recommend surgery to treat certain conditions like degenerative disk disease, sciatica, spinal osteoarthritis, and sometimes ankylosing spondylitis.
If you've been diagnosed with cancer, spinal tumour, or another serious condition, your doctor will discuss treatment options that may include surgery, radiation therapy, or another immediate intervention.
Coping
While not all conditions that cause night-time lower back pain can be prevented, there are several strategies you can implement to help keep your back healthy and hopefully pain-free. Many experts suggest the following to help prevent the progression of pain:
Experiencing night-time lower back pain can make it especially difficult to get quality sleep, which is an important part of recovery for many conditions causing the pain. To improve your sleep while dealing with lower back pain at night, experts recommend these tips:
- Find a sleeping position that supports your specific back condition.
- Choose a mattress that will keep your spine aligned.
- Use pillow support to prop up certain body parts, alleviating pressure and strain on the low back.
Lower back pain while lying down can be especially frustrating, even after you have a diagnosis. When the pain interferes with your ability to get the sleep your body needs to recover, it opens the door to other health issues that are linked to poor sleep.
Any lower back pain that only occurs when you're lying down or regularly wakes you up in the middle of the night should be checked out by a doctor as soon as possible, so you can get back to the restful sleep your body deserves.
