Cupping therapy for back pain and sciatica: what the evidence says

Low back pain is the most common reason people try cupping, and the condition with the most research behind it. That research is also contested. Several meta-analyses report short-term pain relief, the main UK guideline on back pain does not recommend cupping at all, and the two positions are less contradictory than they look once you consider the quality of the trials.

This article sets out what the evidence says about cupping for low back pain and sciatica, how NICE guidance fits in, how to use cupping alongside exercise, where cups are usually placed, and the warning signs that mean you should see a GP. If you are new to cupping, our complete guide to cupping therapy covers the basics first.

Back pain and sciatica: a quick distinction

Most back pain is "non-specific": the NHS notes it often improves on its own within a few weeks, though it can last longer or come back, and the standard advice is to stay active rather than rest in bed [1]. Sciatica is different. It describes pain caused by irritation or compression of the sciatic nerve, usually felt in the buttock and down the back of one leg, sometimes with tingling, numbness or weakness. The NHS says sciatica also usually settles within a few weeks to months, with early gentle movement, heat and pharmacist-advised pain relief as first steps, and physiotherapy if it persists [2].

This matters because almost all the cupping research is in non-specific low back pain. Trials in true sciatica (nerve-root pain) are scarce, so anything said about cupping for sciatica is extrapolation.

What NICE says

NICE guideline NG59, Low back pain and sciatica in over 16s: assessment and management, is the reference point for NHS care in England [3]. It does not mention cupping. What it does say is relevant, though:

• It recommends considering a group exercise programme as a core treatment (recommendation 1.2.2).
• It says manual therapy (spinal manipulation, mobilisation or soft-tissue techniques such as massage) may be considered, but only as part of a package that includes exercise (1.2.7).
• It says "Do not offer acupuncture for managing low back pain with or without sciatica" (1.2.8).

Cupping is not endorsed by NICE. The reasonable reading of NG59 is that passive treatments (things done to you) are at best an add-on to exercise, never a substitute for it. That is exactly how cupping should be framed.

What the systematic reviews say

Here is the evidence, oldest to newest.

Kim et al., 2011. An early systematic review in Evidence-Based Complementary and Alternative Medicine found seven randomised trials of cupping for pain, two in low back pain, both reporting benefit over usual care or analgesia. The authors concluded the trials were few and mostly of poor quality [4].

Moura et al., 2018. A Brazilian systematic review and meta-analysis in Revista Latino-Americana de Enfermagem included 16 studies on chronic back pain, ten of them pooled. Cupping was associated with a statistically significant reduction in pain intensity (p = 0.001), but the authors noted that treatment protocols were not standardised across trials and called for them to be [5].

Cramer et al., 2020. A German meta-analysis of 18 trials (1,172 participants) in The Journal of Pain looked at cupping for chronic pain generally. Cupping produced large short-term pain reductions compared with no treatment, and medium reductions in disability, but was not significantly better than sham cupping or other active treatments for pain. Adverse events were more frequent with cupping than with no treatment [6]. The sham comparison is the important one: against a convincing placebo the advantage largely disappears, which suggests expectation and attention account for a good part of the effect.

Wang et al., 2023. An evidence-mapping study in Frontiers in Neurology pulled together 14 meta-analyses across pain conditions. For low back pain, pooled pain reductions were consistently in cupping's favour, but the certainty of evidence (graded using the GRADE system) ranged from very low to moderate, and no outcome reached high certainty [7].

Zhang et al., 2024. The most recent and methodologically careful review, led from the University of Nottingham and published in Complementary Therapies in Medicine, pooled 11 randomised trials with 921 adults. Cupping improved pain at the end of a two-to-eight-week course compared with medication or usual care, and there was moderate-quality evidence of improved disability at one to six months. However, the benefit was not sustained at one month or three to six months for pain, the subgroup results for dry cupping alone were not statistically significant, and heterogeneity between trials was high [8]. We discuss the dry-versus-wet question in dry cupping vs wet cupping (hijama).

ElMeligie et al., 2024. An umbrella review of these and other systematic reviews in Human Movement rated overall confidence in the reviews as low, mainly because most relied on small trials at high risk of bias [9].

What that adds up to

Put plainly: cupping probably reduces low back pain in the short term more than doing nothing or taking painkillers alone, the effect on disability may last a few months, and it is unclear how much of this is specific to the suction rather than to the attention, touch and expectation of a treatment. For sciatica specifically, there is not enough evidence to say anything confident. That does not make cupping useless. It makes it a low-cost, low-risk comfort measure that some people find helps them keep moving, which is what matters most for recovery.

Using cupping alongside exercise

If you decide to try cupping, use it in the way the evidence and NICE both point towards: as a supporting tool around an active programme.

1. Keep moving first. Walking, swimming, yoga and Pilates are all mentioned by the NHS as helpful for back pain [1]. Cupping is not a reason to skip them.
2. Use cupping before or after activity, not instead of it. Therapists apply cups before mobility work to ease stiffness, or after exercise when muscles feel tight. Either is reasonable; neither has been shown superior.
3. Keep sessions short and spaced. The courses pooled in the most recent meta-analysis lasted two to eight weeks, with the main benefit measured at the end of that period [8]. Within a session, five to ten minutes with the cups on is enough; there is no evidence that longer or more frequent sessions help, and they increase bruising.
4. Track whether it helps you. Rate your pain and function before and after a two-week trial. If nothing changes, stop.
5. Involve your physio. If you are already seeing a physiotherapist, tell them. Many are happy to incorporate dry cupping, and they can rule out reasons not to.

Where to place the cups for back pain

The trials did not use one standard placement, but practice is fairly consistent. These are the common sites used in dry cupping for low back pain:

• Either side of the lumbar spine, over the long erector spinae muscles that run alongside the vertebrae. Cups go on the muscle, two to four finger-widths from the midline, never directly on the spine itself.
• Across the top of the pelvis, over the quadratus lumborum area at the side of the lower back.
• The gluteal muscles, which many people with low back pain or sciatica-type symptoms find tight and tender. Larger cups suit this area.
• Thoracolumbar junction, where the mid-back meets the lower back, if stiffness is felt higher up.

Avoid bony prominences, the kidney area if you have kidney problems, broken or inflamed skin, and varicose veins. Use lighter suction over the lower back than on a thigh, since the tissue is thinner. For a full walk-through of pump strokes, timing and removal, see how to use a cupping set at home. For a home user, a manual pump set with a range of cup sizes, such as those in our cupping therapy collection, is all that is needed; the larger cups are the ones you will use most on the back.

When not to use cupping and when to see a GP

Cupping has general contraindications, including bleeding disorders, anticoagulant medication, pregnancy, active skin disease and some circulatory problems; our article on cupping therapy side effects explains each of them. For back pain, the more important point is that cupping should never delay a medical assessment when one is needed.

The NHS advises seeing a GP if back pain has not improved after a few weeks of self-care, stops you doing daily activities, comes with unexplained weight loss, a lump or swelling, is worse at night or on coughing and sneezing, or sits between the shoulder blades rather than in the lower back [1]. Ask for an urgent GP appointment or call 111 if you also feel hot, shivery or generally unwell, or if the pain is sudden and severe or getting rapidly worse.

Call 999 or go to A&E if back pain or sciatica comes with any of the following, which can indicate cauda equina syndrome, a rare emergency where the nerves at the base of the spine are compressed [1][2]:

• pain, tingling, weakness or numbness in both legs, or sciatica on both sides
• numbness or loss of feeling around the genitals or back passage
• difficulty starting to urinate, being unable to urinate, or loss of bladder or bowel control
• chest pain, or back pain that started after a serious accident

Cupping will not help any of these, and delay could be harmful.

The bottom line

Cupping for low back pain sits in the category of "may help, low risk, not a treatment on its own". The trials point to short-term relief, the certainty is low to moderate, and NICE does not recommend it. Used for a few minutes around the exercise that does the real work, it is a reasonable thing to try. Used as a substitute for movement or a proper assessment, it is not.
