What Causes Sciatica and Why Does the Pain Travel Down My Leg?
Sciatica usually happens when a nerve in your lower back becomes irritated or compressed. Because that nerve travels through your buttock and down your leg, the pain can be felt a long way from where the problem began.
It may feel sharp, burning, electric, or like a deep, constant ache. When it is severe, it can begin controlling your entire day.
Does This Sound Like You?
Before you stand up from the chair, you stop and brace yourself?
You take a deep breath because you know the pain may shoot from your buttock down your leg as soon as you move.
You may have to stand still before taking your first step because the pain takes your breath away.
Perhaps you are struggling to:
- get out of bed or off the sofa
- bend down or put on socks and shoes
- sit comfortably in the car
- stand long enough to cook
- sleep through the night
- work normally
- walk your dog
- meet friends or attend events
You may have started saying no to things because all you can think about is how far you will have to walk, whether there will be somewhere to sit, and how you will get home if the pain worsens.
That is when sciatica becomes more than pain in your leg. It starts restricting your life.
One Woman Felt as Though Her Life Had Stopped
One woman who came to see me had reached the point where sciatica was stopping her from doing almost everything.
She had been off work for a while and had stopped going out with her friends.
Even getting dressed had become difficult. She could not bend forward far enough to touch her feet because the pain was so severe. Putting on socks or ordinary shoes was almost impossible, so she wore shoes that she could simply slip her feet into without bending down.
That may sound small until you cannot put on your own shoes without pain shooting down your leg.
Over approximately five treatments, her pain gradually came back under control. She returned to work, began going out again and could bend and move more comfortably.
She now occasionally feels the symptoms returning, so she chooses to come for treatment approximately every six weeks to help keep the pain settled.
That is one person’s experience. It does not mean everyone will respond in the same way or need the same number of treatments.
What Does Sciatica Feel Like?
Sciatica can feel different from one person to another. You may experience:
- pain beginning in the lower back or buttock
- pain travelling down the back or side of one leg
- burning, stabbing or electric sensations
- a deep ache through the buttock or thigh
- pins and needles, numbness or heaviness
- pain reaching the calf, foot or toes
Some people have back pain as well. Others mainly feel it in the leg.
Why Does the Pain Travel Down My Leg?
The sciatic nerve is connected to nerves that begin in the lower back and continue through the buttock and down the leg.
If one of those nerves becomes irritated, you can feel pain anywhere along its pathway. That is why the severest pain may be in your buttock, thigh, calf, or foot, even though the irritated area is closer to your back.
The simplest way to think about it is this:
The nerve is irritated near your back, but you feel the pain further down the line.
What Causes Sciatica?
One common cause is a bulging or slipped disc. The discs sit between the bones of your spine and act like cushions. If part of a disc pushes outward, it may irritate a nearby nerve.
Other possible causes include narrowing around the nerves, age-related changes, inflammation, a lower-back injury, or lifting and twisting awkwardly.
Sometimes the cause is obvious. At other times, it is not.
Pain travelling down the front of the thigh is not always classic sciatica. It may come from another nerve, the hip or a different structure. That is why the full pattern needs to be assessed rather than every form of leg pain being labelled sciatica.
Why Is It So Hard to Put on Socks or Shoes?
Putting on socks requires you to bend forward, lift your leg and bring your foot towards you.
When the nerve is sensitive, that position may trigger pain through the buttock or down the leg.
You may sit on the edge of the bed trying several positions, wear slip-on shoes or ask someone else to help.
Pain and nerve sensitivity may simply be stopping you from moving normally.
Why Does It Hurt When I Stand Up or Move?
Standing from a chair changes the position of your back, hip and leg at the same time.
When the area is irritated, that first movement may trigger a sharp surge of pain. You may push yourself up using both hands, hold your breath, lean away from the painful side, or pause before walking.
Some people feel better once moving; others worsen with standing or walking. Gentle movement may help prevent stiffness, but do not force yourself through severe pain. Aim for manageable movement without repeatedly triggering a flare-up.
Why Is Sciatica Worse at Night?
Turning in bed may send pain down the leg, while lying still can leave you stiff.
A pillow between your knees when sleeping on your side, or beneath your knees when lying on your back, may help. Use the position that increases your symptoms least.
How May Acupuncture Help Sciatic Pain?
When you come to Galway Acupuncture Hub, I do not only ask where the pain is. I want to understand what it is stopping you from doing.
Can you sleep? Can you work? Can you put on your socks? Can you walk your dog? Have you stopped going out because you are worried about the pain?
I also ask where it begins, where it travels, what aggravates it, and whether there is numbness, tingling, or weakness.
Treatment is then adapted to your individual symptoms.
Acupuncture may help some people reduce pain, settle muscular tension and move more comfortably. Depending on your presentation, I may also use cupping, gua sha, tui na or other suitable techniques.
The aim is to reduce the hold the pain has over your day so that you can begin returning to the things you have stopped doing.
Results vary, and acupuncture cannot guarantee that sciatica will disappear. It can support, but not replace, appropriate medical assessment and treatment.
How Many Treatments Might I Need?
There is no single answer.
It depends on the severity, duration, presence of numbness or weakness, and how your body responds. Some people notice changes relatively quickly; others need more time.
We look for practical improvements:
- Standing more easily
- Sleeping for longer
- Putting on shoes
- Walking further
- Returning to work
- Meeting friends again
Those everyday changes matter because they show that the pain is beginning to lose its grip on your life.
When Should You Contact Your GP?
Speak to your GP if:
- The pain is severe, worsening or not improving
- It is preventing normal daily activities
- You have persistent numbness or pins and needles
- Your leg or foot feels weak
- Your foot begins catching or dragging
- The pain followed a significant fall or accident
- You have a fever, unexplained weight loss or feel generally unwell
Seek urgent medical help if you develop numbness around your bottom, genitals or inner thighs; difficulty passing urine; loss of bladder or bowel control; or severe weakness in both legs.
These symptoms are uncommon, but they need immediate assessment.
Frequently Asked Questions
Can You Have Sciatica Without Back Pain?
Yes. Some people have very little back pain but severe pain in the buttock, thigh, calf or foot.
Can Sciatica Cause Numbness or Tingling?
Yes. An irritated nerve may cause pins and needles, numbness or altered sensation. Persistent numbness or weakness should be assessed.
Does Severe Pain Mean I Have Serious Damage?
Not necessarily. Nerve pain can be extremely intense even when permanent damage has not occurred. Severe or worsening symptoms should still be checked.
Can Acupuncture Cure Sciatica?
I would never promise that acupuncture can cure sciatica. It may help some people reduce pain and improve movement, but results vary.
Has Sciatica Started Controlling Your Life?
Perhaps you are bracing yourself every time you stand.
Perhaps you cannot put on your shoes, sleep properly, work comfortably, walk your dog or meet your friends.
You do not need to minimise how much the pain is affecting you.
I regularly see people from Loughrea and across County Galway whose sciatic pain has begun affecting their work, sleep and everyday life.
Call me for a chat at Galway Acupuncture Hub in Loughrea. Tell me where the pain travels and what it is stopping you from doing.
We can discuss whether acupuncture may be suitable for you and whether you should also speak with your GP.
