What the best trial found
In 2024 a randomised trial across six hospitals took 216 people who had lived with sciatica from a herniated disc for months. Half had real acupuncture and half had sham needling that did not penetrate properly. Both groups had ten sessions over four weeks.
At week four, leg pain in the acupuncture group had dropped by about 31 points on a 100-point scale, against about 15 in the sham group. Disability scores improved by 13 points against 5. The difference held at the one-year follow-up, and no serious side effects were recorded.
That is a meaningful result for a condition where most treatments show small effects. It is also one trial, in people with a confirmed disc cause and pain lasting over three months.
What UK guidance says
NICE guideline NG59, published in 2016, advises against offering acupuncture for low back pain with or without sciatica. The trials available then showed real acupuncture performing about the same as sham.
The 2024 trial is newer than that guidance and points the other way for chronic, disc-related leg pain. You should know both facts before you book. The guidance still puts exercise, staying active and self-management first, and so does this clinic.
Sciatica from a disc usually improves by itself. Most people are substantially better within 12 weeks. Treatment earns its fee by making those weeks more bearable and keeping you moving through them.
What a course looks like
A plan built on the trial is two to three sessions a week for the first fortnight, then two a week. For someone working near Holborn that is a lunchtime or after-work slot on fixed days, so it happens.
Budget for a slower problem than a simple back strain. In UK clinic records we analysed for adults under 40, about four in ten people with sciatica needed more than three appointments, because an irritated nerve settles more slowly than muscle.
How to judge it
- Before session one. Score your leg pain out of 10 and note how far you can walk before it builds. Write both down.
- After session four. Score again. A drop of two points or more, or a clear gain in walking distance, is the signal to continue.
- No change by session six. Stop and change the plan. More of the same is unlikely to turn it.
- Session ten. Review, then space out or finish.
Needles go in around the lower back, the buttock and along the line of the leg pain. They stay in for 20 to 30 minutes. Most people feel a dull ache or heaviness at the point, which fades within a minute.
Every session should end with what you do before the next one: walking targets, the positions that ease the leg, and the first loading exercises. See the acupuncture page for how sessions run.
What acupuncture cannot do
Know the limits before you spend on it.
- Disc size. Needling leaves the disc as it is. Discs reduce by themselves over months.
- Strength. A foot that has gone weak goes the medical route first, then graded strengthening.
- Your own work. Walking and loading stay in the plan throughout. People who stay active recover faster than people who rest and wait.
- Other causes. Leg pain from the hip joint or a hamstring tendon is a poor fit for this approach. Those are treated differently, which is why the first session starts with testing.
Stop and get seen if
- Numbness around the groin, genitals or inner thighs, or any change in bladder or bowel control. Go to A&E the same day.
- Weakness that is getting worse, or a foot that drags or slaps.
- Pain down both legs at once.
- Fever, unexplained weight loss or a history of cancer alongside new leg pain.
- Severe pain after a fall or accident.
Straight answers
How many acupuncture sessions does sciatica need?
The trial used ten over four weeks. In practice, review at session four and again at six. If the leg pain has dropped by two points out of ten, carry on to ten. If nothing has moved by six, stop.
Does acupuncture for sciatica hurt?
The needles are about a quarter of a millimetre thick. You feel a brief prick, then a dull ache or heaviness around the point. Tell the therapist if a needle produces a sharp, electric feeling down the leg, and it gets repositioned.
Acupuncture or exercise for sciatica?
Exercise and staying active come first, because they have the widest evidence and they are what keeps the problem from returning. Acupuncture sits alongside for people whose leg pain is stopping them from doing that work.
