Low Back Pain

What is Low Back Pain?

Low back pain is pain felt in the lower part of the back, and it is the leading cause of disability worldwide. For nearly all people, no specific structural cause can be identified, and only a small share have a clear cause such as a fracture, tumor or infection.^[1]

Common symptoms

Low back pain usually feels like a dull ache or sharp pain across the lower back, often with stiffness and muscle tightness. It may spread into the buttock or leg.^[2]

Leg numbness, tingling or weakness suggests that a nerve is involved, and these symptoms need a medical evaluation.^[2]

Pain that lasts less than about 6 weeks is called acute, and pain that continues beyond 12 weeks is called chronic.

Causes and risk factors

Most low back pain is called non-specific, meaning the pain cannot be traced to one tissue. Muscles, joints, discs, ligaments and nerves in the lower back can all contribute.^{[1, 2]}

People with physically demanding jobs, other physical or mental health conditions, smokers and people with obesity are at greatest risk. Most new episodes improve quickly, but recurrence is common, and high initial pain, psychological distress and pain in several body areas raise the risk that it becomes persistent.^[1]

How it is diagnosed and treated conventionally

Diagnosis rests on your history and a physical exam, checking mainly for signs of serious causes or nerve involvement. Imaging is not specific enough to explain most low back pain, so it is kept for particular concerns.^[2]

Treatment usually starts with self-care, staying active and pain medicines, together with physical therapies and psychological approaches when appropriate.^[2] An overview of Cochrane reviews found that exercise therapy probably reduces pain and improves function in chronic low back pain, and that advice to stay active probably beats advice to rest in acute low back pain.^[3] For stubborn pain, injections and surgery are options in carefully selected people.^[2]

Why Low Back Pain calls for a whole-person approach

Low back pain is rarely just a damaged structure. Biological, psychological and social factors interact, which is why a biopsychosocial approach is recommended and treatment that addresses only one cause often falls short.^[2]

Care that also considers inflammation, muscle tension, pain sensitivity and stress is therefore a reasonable addition to the care your physician or therapist directs.

Inflammation and nerve sensitivity

A review of chronic low back pain mechanisms describes inflammation in lumbar tissues that can lower the threshold of pain nerves to fire, and central sensitization, in which the brain and spinal cord amplify pain signals.^[4] This is mostly mechanistic research, so it explains how pain may persist, not how any one treatment works.

Muscle tension and movement

Muscles, fascia and ligaments in the lower back contain pain receptors, and degeneration or strain of these tissues can contribute to pain.^[4] Exercise therapy is a central part of conventional treatment.^[3]

Stress, mood and pain processing

Psychological distress and pain cognitions have important roles in whether low back pain becomes persistent and disabling.^[1] Psychological therapies probably reduce pain slightly in chronic low back pain.^[3]

Body weight and general health

Obesity, smoking and other health conditions are linked to a greater risk of reporting low back pain.^[1]

Acupuncture for Low Back Pain

What the research shows

Research suggests acupuncture can reduce low back pain and improve function, but the effects are small and the certainty of the evidence is low to moderate. Part of the benefit may come from non-specific effects such as expectation and the treatment experience.

A 2020 Cochrane review of 33 trials with 8,270 people with chronic non-specific low back pain found that acupuncture gave greater pain relief and function than no treatment, with moderate-certainty evidence. Compared with sham acupuncture, the pain difference was small and did not reach the threshold for clinical importance, and function was not clearly better. The authors noted that most trials had a high risk of bias.^[5]

A 2025 overview of Cochrane reviews was somewhat more positive. It concluded that acupuncture probably improves function slightly compared with sham acupuncture, and probably reduces pain and improves function compared with no treatment, in chronic low back pain.^[3] A review for the American College of Physicians guideline also found low to moderate strength evidence for acupuncture in chronic low back pain, with small to moderate and generally short-term effects, and low-strength evidence for acute low back pain.^[6] A meta-analysis of 11 trials with 707 patients found modest improvements in pain with acupuncture in acute low back pain, with caution because the trials were small.^[7]

Sham acupuncture may not be a true placebo. A network meta-analysis of 10 trials found that sham needling at the same points used in real acupuncture produced better results than sham needling at different points, which may lead to underestimating acupuncture's effect.^[8] In a double-blind trial of 121 adults, real electroacupuncture was not significantly better than sham for pain, but improved disability scores more.^[9] A review of acupoint selection found that acupuncture reduced pain compared with control, with no clear best point combination.^[10]

How acupuncture may work

Researchers propose that acupuncture influences pain through nerves and immune cells near the needle and through pain pathways in the spinal cord and brain.^[11] This work comes largely from laboratory studies of inflammatory pain, so it is a proposed explanation and not a settled fact for low back pain.

What treatment involves

Treatment uses fine, sterile, single-use needles placed at points on the lower back, hips and legs, usually left in place for about 20 to 40 minutes. Mild electrical stimulation or moxibustion may be added. One double-blind trial gave 12 sessions over 6 weeks.^[9] We reassess after a short course of visits.

Serious problems are rare. In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, soreness or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[12] The Cochrane review lists insertion point pain, bruising, bleeding and worse back pain among the commonly reported events.^[5] Tell the practitioner first if you have a bleeding disorder, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture).

Ayurvedic medicine for Low Back Pain

The Ayurvedic view

Ayurveda describes low back pain as Katigraha or Kati Graha, a condition in which the lower back is afflicted by Vata. A traditional variant, Sama Vata, involves Ama, a term for the products of impaired digestion and metabolism, and is described as presenting with pain and stiffness.^[13] These are traditional categories for choosing treatment, not biomedical diagnoses.

Therapies that may be used

Care is chosen for the individual and traditionally combines:

• Diet and daily routine intended to calm Vata, such as warm, regular meals and steady sleep
• Warm oil massage and local sweating therapy such as poultices (Upanaha Sweda)^[13]
• Kati Basti, in which warm medicated oil is held over the lower back in a ring of dough^[14]
• Herbs and formulas, such as guggulu-based formulas, prescribed individually
• Medicated enema therapy (Basti) from Panchakarma, which has been studied in lumbar spondylosis^[15]

Panchakarma procedures are not appropriate during pregnancy, acute illness or frailty, or before red-flag symptoms have been medically assessed.

What the research shows

The research on Ayurveda for low back pain is limited. It consists of a few small trials and uncontrolled studies, none placebo-controlled.

In a randomized trial of 40 people with chronic low back pain, adding Kati Basti to a one-week yoga program did not reduce pain, disability or depression more than yoga alone, though both groups improved.^[14] A randomized comparison of poultice treatments found that matching the poultice to the Ayurvedic stage of the pain worked better than a single type, but it had no untreated or placebo group.^[13] A 15-day study of 23 patients given enema therapy reported improved symptoms and disability scores without a comparison group.^[15]

A systematic review of 113 Ayush studies in lumbar and cervical spondylosis found that only about one in eight reported any adverse events, which suggests that adverse events may be under-reported.^[16]

Herbal medicine for Low Back Pain

Herbs and formulas that have been studied

Most research covers Western herbs and Chinese medicine for non-specific low back pain. The herbs studied include cayenne (capsicum) cream or plaster applied to the skin, devil's claw and white willow bark taken by mouth.^[17] Ayurvedic practice uses herbs such as guggulu-based formulas, but none have a placebo-controlled trial for low back pain in our search.

Herbal preparations applied to the skin are also part of the clinic's transdermal medication therapy.

What the research shows

The evidence for herbal medicine is mixed: moderate quality for capsicum applied to the skin, and low or very low quality for most other herbs. A Cochrane review of 14 trials with 2,050 participants found that capsicum cream or plaster probably reduces chronic low back pain more than placebo (moderate-quality evidence). It found low to moderate-quality evidence for short-term pain relief with devil's claw and white willow bark. Evidence for other herbs was of low or very low quality, and the authors noted that reporting in these trials was poor and no significant adverse events were seen.^[17]

A large meta-analysis of Chinese medicine for neck and back pain mostly addressed acupuncture, cupping and manual therapies, so it does not show that oral Chinese herbs work for low back pain.^[18]

Safety and herb-drug interactions

Herbs are active substances and can interact with medicines. Case reports describe serious bleeding or clotting events when warfarin was combined with herbs including dang gui (Angelica sinensis), dan shen (Salvia miltiorrhiza), ginger, ginseng and Boswellia.^[19] White willow bark contains a compound related to aspirin, so people who take blood thinners or anti-inflammatory medicines need a practitioner's review before using herbs for pain.^[17]

In one study, about one fifth of Ayurvedic products bought online contained detectable lead, mercury or arsenic.^[20] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding, or have liver or kidney disease.

Translating traditional medicine into modern biological language

The links drawn here are interpretation, not equivalence. Chinese medicine often describes low back pain as obstruction of qi and blood in the channels, sometimes with cold, damp or kidney weakness. Researchers study things that loosely parallel this, such as inflammation in lumbar tissues, muscle tension and sensitization of pain pathways.^{[4, 11]}

Ayurveda's aggravated Vata describes stiffness, dryness and pain in the lower back. Researchers describe chronic low back pain as a mix of peripheral inflammation and central pain amplification.^[4] No study has shown that a dosha or a pattern corresponds to a specific biological process.

How this care fits with your medical care

Integrative care for low back pain is complementary. Keep your physician or physical therapist, and do not stop or change prescribed medicines or planned injections or surgery without your prescriber. We do not diagnose the cause of back pain, so new, severe or unexplained back pain should be medically evaluated first.

Please bring your diagnosis, any imaging reports, a full list of medicines and supplements, and details of any injections or surgery. Exercise has some of the best support in conventional care, and acupuncture is best used together with it.^[3]

When to seek urgent medical care

Some back pain comes from a serious cause such as a fracture, infection, tumor or severe nerve compression.^[1]

• New trouble passing urine, or loss of bladder or bowel control
• Numbness in the groin, genitals or inner thighs (the "saddle" area)
• Leg weakness that is new or getting worse
• Back pain with fever, unexplained weight loss or a history of cancer
• Pain after a fall, accident or other injury, especially in older adults or people with osteoporosis
• Severe pain that is not eased by rest or that wakes you at night

If any of these occur, call 911 or go to the nearest emergency department.
