Let’s clear up some things

Firstly, Sciatica isn’t a diagnosis it’s a symptom, so if you’ve been to see your GP with your back pain and leg pain and they’ve told you that you have sciatica, well great, you already knew that, it’s why you went to the GP in the first place. What you need to know is what is causing the pain and how to get rid of it.

Sciatica is a term that is often used incorrectly to explain low back pain with leg pain. Many people who have back and leg pain have been told by their GP or a friend who has experienced similar symptoms that they have sciatica….but is it true sciatica? In our experience, it’s usually not.

Think of nerve tissue as the spoilt brat of the body. When conditions aren’t just right, your nerves will be the first to flare up and have a hissy fit. The sciatic nerve is the longest and widest nerve in the body; if it’s irritated, you’ll definitely know about it.

What is sciatica really?

True sciatica is caused by pressure on the sciatic nerve at the nerve root as it exits the spine in the lower back.

Everyones experience might be different. Most common symptoms are pain that may be electric and sharp in nature that zips down the back of the leg from the lumbar spine to the foot. It might even make your leg momentarily give way. Burning, tingling, numbness or weakness are all symptoms of nerve irritation.

But just because you have pain that spreads into the leg doesn’t mean you have sciatica.

Muscles are a very much overlooked cause of leg and buttock pain. There are multiple muscles in the lower back and buttocks that can refer pain down the leg. The piriformis and gluteal muscles in particular are very good at mimicking ‘sciatica’ and in my experience, these are the true cause of the buttock and leg pain, not the sciatic nerve.

So is it sciatica, or isn’t it?

Here are some questions you should ask yourself if you have lower back pain with leg pain.

1. Did you do anything to suddenly bring about back pain which was then followed by pain spreading into the leg within the week?

The most common mechanism of injuring the discs in the lower back is flexing forward combined with a twist. This action is not tolerated well by the discs which may bulge or herniate onto the nerve roots. The most common discs to be injured are the ones at the very bottom of the spine, which is why the sciatic nerve is the most commonly irritated nerve.

Important note: If you injured your back while lifting, it’s not what you lifted, or how heavy it was…it’s how you lifted it! you could have been picking up a feather; the flex-twist combo is a BIG no-no for your lower back. One thing that I hear an awful lot from my patients is “but I was only just…” or “…but it wasn’t even heavy”. It doesn’t make a difference. You would be amazed at the level of force that your Lumbar discs can endure. Trust me, it’s wasn’t the weight you lifted. Almost all lumbar disc injuries that I see in practice occurred whilst doing some petty daily activity like loading the washing machine, lifting the toddler out of the high chair or getting in or out of the car.


2. Is the pain coming from your back? or is it coming from your buttocks?

The Piriformis muscle is a muscle that crosses the pelvis and lies over the top of the sciatic nerve as it passes into the leg. If the piriformis becomes overly tight or you receive a trauma to the buttocks then the sciatic nerve can become irritated. It may be hard to differentiate though because the piriformis itself can refer pain down the leg with or without compressing the sciatic nerve.

Some particular activities that may aggravate the piriformis include a lot of walking on uneven surfaces, using the hip abduction machine in the gym, prolonged sitting and a lot of time spent driving.

3. Does the leg pain go past the knee?

As a general rule, true sciatica will cause leg pain that spreads past the knee, though not always. It may depend on the severity of the nerve irritation. There are several clinical tests that can help to differentiate between pain arising from the nerve root itself, a nerve that is irritated further along the nerve bed or a muscle that has a referral pattern similar to the sciatic nerve. That’s why it is best to consult with a musculoskeletal specialist like a chiropractor, physiotherapist or osteopath to get the correct diagnosis and plan of management.

If your pain is coming from your buttocks, then try some of these stretches and hopefully they will give you some relief.

Glute & Piriformis stretches
Try them for pain in the buttocks region, and to release tension that may be irritating the sciatic nerve

The thing to remember about stretches, is that they are more effective when they are done little and often.

Muscles have their own memory and will revert back to their usual state of contracture quite quickly. If you have chronically tight muscles then brutally stretching them for half an hour a day will not be an effective way of releasing that tension. You will find that within a few hours and certainly within a couple of days that the muscle just springs back to being really tight.

Stretches aren’t a one and done kind of thing; keep going back and doing the same stretches as many times a day as you can, just for a few minutes at a time and the muscles will start to lengthen and relax.


Sciatica and disc injuries

If your think you have injured a disc which may be compressing your sciatic nerve, then I would strongly advise that you visit a Chiropractor or other musculoskeletal specialist. Discs can be tricky and it’s really not worth the risk of further injury by doing the wrong exercises and activities. I haven’t included any exercises here for disc injuries because it’s not something that you should try to diagnose yourself. Not all disc injuries are the same and therefore there isn’t one set of exercises to suit everyone. But I have included top-tips which will help to prevent further injury to your discs, allow you to continue your day and take the edge off while your disc is trying to heal.


Top Tips for looking after your lumbar discs


  1. Learn to hinge from your hip joints when leaning forward – your hips are ball and socket joints; like your shoulders, they are designed to have a large range of movement, so use them to bend forward so your spine doesn’t have to.
  2. Lie, don’t sit – Sitting is detrimental to your discs. If you have injured a disc, then sitting for prolonged periods will be uncomfortable. Our advice is to lay down on your back with your knees bent at 45 degrees. Bending the knees decreases the pressure on the discs. If you have injured a disc you will likely feel relief in this position.
  3. Keep mobile – I know this sounds like something you don’t want to be doing if you have an injured discs because moving around can be painful, but staying mobile is really important. Discs are a very poorly vascularised structure which means that they are bad healers. This is why disc injuries can take so long to go away and why it is so easy to get knocked back to square one – it’s very frustrating. Your discs need you to move so that blood and nutrients needed for the healing process can be pumped into them, this isn’t going to happen if you just stay in bed all day. You’ll want to take things easy but complete rest is going to prolong your discomfort and healing.
  4. As your pain levels start to reduce, learn to activate your core muscles. Our spines are like a tower that has supports on all 4 sides. Unfortunately for most of us, that support is left to the muscles of the back while the muscles on the front and sides are having a nice long holiday. This is why back pain is so common. There is only so long your back muscles can carry you without the help of other supporting muscle groups.
  5. Practice maintaining a neutral spine. The spine naturally has lazy S-shaped curves in the neutral position. These are important because this is the position where your spine can optimally absorb forces. If you remove 1 curve (let’s say the lumbar curve) by sitting, then you have taken away your lumbar spine’s ability to absorb the forces; not a great idea, especially if you have already got a lower back injury.
