Understanding Sciatica
Sciatica is pain along the sciatic nerve. This nerve runs from the lower back. It goes through the pelvis and down each leg.
Related glossary terms: Disc Herniation, Pinched Nerve, Lower Back Pain.
The nerve can get pressed or irritated. This causes pain, numbness. Or tingling. You may feel weak in your back, butt. Or leg.
The pain feels sharp like a shock. It can be mild or very bad. Sciatica is not a disease. It's a sign of another problem.
That problem might be a herniated disc. It could also be a spine that's out of place.
Most people feel sciatica on one side. Pain gets worse when sitting, coughing. Or sneezing.
It can make walking or standing hard. Sciatica often gets better in a few weeks. Rest, ice, heat. And stretching help.
But if pain is bad or lasts too long, see a doctor. Also see one if you lose bladder or bowel control.
How Sciatica Works?
The sciatic nerve is the longest nerve. It starts in the lower back. Five nerve roots make it up.
If one root gets squeezed, it sends pain signals. The pain follows the nerve path. A herniated disc often causes this.
Discs are cushions between bones. If a disc slips, it can press on nerves. This is called a herniated disc.
Other causes include spinal stenosis. That means the spine's path gets too narrow. Bone spurs can also press on nerves.
Bone spurs are extra bone growths. Tight muscles in the butt can cause pain too. This is called piriformis syndrome.
Pain can be sharp or dull. It may start in the back. Then it moves down the leg.
Sometimes it reaches the foot. You may feel numbness or tingling. Weakness in the leg or foot is common too.
Doctors check your body and health history. They may use X-rays or MRIs. These tests find what's pressing the nerve.
Why Sciatica Matters?
Sciatica can hurt daily life. Even mild pain makes sitting hard. Severe cases limit movement.
Pain can stop you from working. It can also keep you from sleeping. Ignoring it can make things worse.
Early help eases pain. It stops long-term nerve damage. This makes life better.
Sciatica warns about spine problems. Fixing posture or muscle issues helps. This stops future pain.
Chiropractic care can help. So can physical therapy. Lifestyle changes work too.
These fixes work for most people. Get help before pain gets bad.
When Sciatica Matters Most?
See a doctor if pain is very bad. Also if it lasts weeks. Or if your leg gets weak.
Loss of bladder or bowel control is serious. This may mean cauda equina syndrome. It needs emergency care.
Some jobs raise sciatica risk. Heavy lifting can cause it. So can sitting too long.
Pregnant women may feel sciatica. The baby can press on the nerve. Athletes and older adults get it more.
People with diabetes or obesity get it too. Their spines feel more strain. Nerves may be more sensitive.
Early help keeps you moving. Chiropractic care can help. So can stretching.
Changing your work setup helps too. This stops long-term pain.
