Sciatica: what it really is and what helps
Sciatica is pain, tingling, numbness or weakness that travels down the leg because one of the nerve roots that form the sciatic nerve is irritated or compressed, most often by a disc in the lower back. Not every pain that runs down the leg is sciatica, and the difference matters because the treatment is different. The good news: true sciatica usually improves over weeks to months with the right care and movement.
What sciatica really is
The sciatic nerve, the largest in the body, is formed from several nerve roots that leave the lower spine, join in the pelvis and run down the back of the leg to the foot.
When one of those roots is pressed on or irritated, usually by disc material pushing out through a weak spot in the disc wall, symptoms can appear anywhere along the nerve. Doctors call this radiculopathy.
Sciatica is perhaps the most misused word in the back pain vocabulary.
People often call any pain from the back into the leg “sciatica”. Clinically it is much more specific, so it should be a diagnosis made after an examination, not a label based on where the pain travels.
Signs that point to true sciatica
- The pain follows a defined line down the leg, often below the knee, rather than being vague and spread out.
- There is numbness, pins and needles or weakness as well as pain.
- It gets worse with things that raise pressure in the disc: sitting, bending forward, coughing or sneezing.
- Specific tests during an examination, such as raising the straight leg, bring on the leg symptoms.
The pattern can even suggest the level: L4/L5 often sends symptoms to the top of the foot and big toe, L5/S1 to the outer heel and little toe. These patterns are not absolute, but they help an experienced clinician before any scan.
When leg pain is not sciatica
Other structures can cause similar buttock and thigh pain:
- The sacroiliac joint, where the spine meets the pelvis, is one of the most commonly missed causes.
- The piriformis muscle, deep in the buttock, sits next to the sciatic nerve and can irritate it, especially with long sitting.
- The facet joints, the small joints at the back of each spinal level.
- The hip joint itself.
In his book, Dr Zano describes a patient told he had sciatica, whose MRI showed a small disc bulge. On examination the nerve tests were negative and the pain came from the sacroiliac joint. The lesson: the examination should guide treatment, not the label or the scan alone.
What usually happens over time
For most people with disc related sciatica, the natural direction is towards improvement. Repeat scans show that many herniated discs shrink on their own as the body gradually clears the material that has pushed out.
This takes weeks to months, and progress is rarely smooth. Typically the leg pain eases first, then numbness and tingling, and back pain settles last. Knowing this helps you not give up too early or panic on a bad day.
What helps with sciatica
An accurate diagnosis
Everything starts with finding where the pain really comes from. Treating the wrong structure is a common reason sciatica drags on.
Conservative care
For most disc problems, the first line is conservative care: manual therapy chosen for your situation, targeted exercise, easing off activities that keep irritating the nerve, and pain relief from your doctor if needed. At Bodywerks this means chiropractic care, with acupuncture or dry needling when appropriate. With signs of a significant nerve problem, techniques are chosen carefully and your strength and sensation are rechecked. Chiropractic care is not right for everyone, and if it is not right for you, we will say so.
A plan over weeks, not a single visit
Sciatica usually needs regular care for a while, so we offer a Sciatica and Disc programme: €720 for 12 weeks with as many visits as your plan needs. Whether it suits you is decided together at your first visit.
What you can do at home
- Keep moving as much as your pain allows. Long bed rest slows recovery. Gentle walks, building up towards 20 to 30 minutes a day, help most people.
- Break up sitting. Get up every 20 to 30 minutes, even briefly, and support the curve of your lower back with a lumbar roll.
- Use heat or ice for comfort. Ice often suits the first day or two of a flare, heat later. Use whichever helps.
- Use the traffic light rule for exercise. Mild discomfort is fine. Moderate pain that does not build and settles within 24 hours is usually acceptable. Pain that climbs during the set or is worse the next day means the exercise needs changing.
- Be careful with sit-ups, crunches and deep forward bends while a disc is irritated. They increase pressure in the disc.
Exercises found online are not matched to your diagnosis, so ask your practitioner to tailor them. And if you need heat, ice or painkillers almost every day, treat that as a sign the cause has not yet been properly assessed.
When to see a doctor straight away
- New difficulty passing urine, or loss of bladder or bowel control.
- Numbness in the saddle area: groin, inner thighs, genitals or buttocks.
- Weakness in one or both legs that is getting worse, or a foot that starts to drag.
- Sciatica with fever, unexplained weight loss, a history of cancer, severe pain at night, or after a significant fall or accident.
The first three can signal cauda equina syndrome: go to the emergency department. For the others, see a doctor promptly. More in our article on back pain red flags.
Frequently asked questions
How long does sciatica last?
It varies. Many people improve over weeks to a few months. Recovery is rarely a straight line, so a bad day does not mean you are back to square one.
Should I rest in bed with sciatica?
A little rest in the first days can help, but long bed rest slows recovery. Staying as active as your pain allows, with gentle walking, is generally better.
Can a chiropractor help with sciatica?
For many people, chiropractic care is part of conservative treatment for sciatica, together with exercise and activity advice. It starts with an examination to confirm where the pain comes from and rule out signs that need a doctor. It is not suitable for everyone.
Is all leg pain from the back sciatica?
No. The sacroiliac joint, piriformis muscle, small spinal joints and hip can all cause buttock and thigh pain. An examination tells them apart, and treatment differs.
If pain runs down your leg and you want to know why, book online at our clinics in Limassol and Nicosia, or message us on WhatsApp. The first visit is €70 and includes treatment when appropriate, with no charge if treatment is not suitable or an X-ray is needed first.
