Low back pain

Your lower back can sometimes feel sore.

This pain is between your ribs and your bottom. It can feel like a dull ache. It can also feel sharp.

Many people feel better in a few weeks. Most people find relief very soon. Sometimes, moving or lifting things can cause the pain.

Small cushions sit between your bones. These cushions help protect your back. If they get hurt, your back may ache.

It is good to keep moving. You should do normal things as much as you can. This can help you get well.

Have you ever had a sore back?

Your lower back is the area between your ribs and your bottom. It contains bones called vertebrae. Small cushions called intervertebral discs sit between these bones. These discs act like pillows to protect your spine.

Many people feel back pain. It can feel like a dull ache or a sharp sting. Most people feel better within six weeks. This is called acute pain. If pain lasts more than 12 weeks, it is called chronic pain.

Pain can happen for many reasons. Sometimes, it comes from muscle or joint strain. A disc can also become damaged. This is called a herniated disc. When this happens, the disc material may press on a nerve. This can cause pain to travel down your legs. This specific feeling is called sciatica.

Doctors use many ways to help. Heat, massage, or acupuncture can help the pain. It is important to keep moving as much as you can.

Some people have pain because of how their brain processes signals. This can make a small event feel like a lot of pain. This is common in chronic pain. Many people in the world deal with this every day.

Low back pain is a common problem for many people. It happens in the area between the lower ribs and the buttocks. This part of the body includes bones called vertebrae and muscles that hold you up.

The pain can feel like a dull ache that stays the same. It can also feel like a sudden, sharp sting. Doctors group pain by how long it lasts. Pain that stays for less than six weeks is called acute pain. If it lasts six to 12 weeks, it is sub-chronic. Pain that lasts more than 12 weeks is called chronic pain.

Your back stays strong because of a special way it works. Between your vertebrae are soft cushions called intervertebral discs. These discs have a jelly-like center and a tough outer ring. They act like pillows to stop your bones from rubbing together.

Nerves run through small openings between these bones to send messages. When a disc gets damaged, it is called a herniated disc. This can happen if the disc material pushes on a nerve. This might cause a feeling called sciatica, which travels down your legs. Sometimes, muscles like the multifidus do not work right during recovery. This can make the pain come back later.

Scientists and doctors have studied how we feel pain for a long time. Pain is not just a feeling; it is a signal from the body. The process of feeling pain has four main steps. First, there is transduction, where nerve cells turn an event into an electrical signal. Next is transmission, when the signal travels through the spinal cord to the brain. Then comes perception, where the brain figures out what the signal means. Finally, there is modulation, where the brain can change the strength of the signal.

In chronic pain, these steps might not work the way they should.

Many facts show how widespread this issue is. About 40% of people will have low back pain at some point. In developed countries, that number can be as high as 80%. Right now, about 632 million people are dealing with it. This is about 9% to 12% of the world's population. Most people first feel this pain between the ages of 20 and 40. Women and older people often have higher rates of pain or disability. The World Health Organization said in 2023 that this is a top medical condition. Many people can benefit from better rehabilitation programs.

Most people find relief using simple ways to help the body. Doctors often suggest non-medication treatments first. These include using heat, getting a massage, or trying acupuncture. It is also important to keep doing normal activities as much as you can. If those do not work, doctors might suggest medicines called NSAIDs. For some, surgery might help if a disc is causing big problems. However, surgery does not always help with other types of pain. Understanding how your back works helps you take better care of it.

Low back pain, also known as lumbago, is a very common medical condition. It affects the area between the lower edge of the ribs and the lower fold of the buttocks.

This region includes five lumbar vertebrae, labeled L1 through L5, and the sacrum. The condition involves the muscles, nerves, and bones of the lower back. It can feel like a dull, constant ache or a sudden, sharp sensation. Because it is so widespread, it is a major cause of disability and lost productivity worldwide.

Doctors classify low back pain based on how long the symptoms last. Acute pain is defined as lasting less than six weeks. Sub-chronic pain lasts between six and twelve weeks. Chronic pain is any pain that lasts for more than twelve weeks or three months. Most people find that their symptoms improve within a few weeks. In fact, between 40% and 90% of people recover within six weeks of the pain starting.

The structure of the lower back is quite complex. Between the vertebrae are fibrocartilaginous intervertebral discs. These discs have a gelatinous core surrounded by a fibrous ring. They act as cushions to prevent the vertebrae from rubbing together. They also help protect the spinal cord. Nerves pass through specific openings between the vertebrae to send sensory input and muscle messages. Stability is provided by the ligaments and muscles, such as the multifidus muscles. These muscles run along the spine to keep it straight and stable during walking or lifting.

Pain sensation happens through a specific four-step process. First is transduction, where sensory nerve cells convert a stimulus into an electrical signal. Second is transmission, where these signals travel through the spinal cord to the brain stem. Third is perception, where the brain processes these signals and gives them context. Finally, there is modulation, where the brain can increase or decrease the release of neurotransmitters to change the signal. In chronic pain, the pain processing system may malfunction. This can cause the body to feel intense pain in response to non-serious events.

There are several different types of causes for low back pain. Mechanical causes include muscle strains, spasms, or osteoarthritis. A herniated disc occurs when disc material pushes on a nerve root. This can cause sciatica, which is pain radiating down the legs. Non-mechanical causes include infections, such as osteomyelitis, or tumors. Inflammatory causes include conditions like ankylosing spondylitis. Other factors like obesity, smoking, and stress can also contribute to the problem. For women, conditions like endometriosis or uterine fibroids may cause pain.

Managing low back pain often begins with non-medication treatments. These include superficial heat, massage, acupuncture, or spinal manipulation. Doctors recommend continuing normal activity as much as the pain allows. If these methods are not enough, NSAIDs may be used. For severe cases, opioids are sometimes used, though they carry risks of addiction and overdose. Surgery is usually only considered for specific issues like spinal stenosis or disc-related disability. For many, counseling or antidepressants can help manage the mood changes that often accompany chronic pain.

Low back pain is a massive global health issue. Approximately 9% to 12% of people, or about 632 million individuals, have pain at any given time. About 40% of people will experience it during their lives, and this can reach 80% in developed countries. Most people first experience this difficulty between the ages of 20 and 40. Women and older people often report higher rates of pain and disability. In 2023, the World Health Organization identified lower back pain as a top medical condition. They noted that many people worldwide could benefit from improved rehabilitation programs.
