Pain that shoots from your lower back down one leg is often sciatica. Here's what causes it, what usually helps, and the warning signs that need care right away.
It often starts as an ache in the lower back that seems easy to ignore. Then, a day or two later, a sharp, electric pain shoots through the buttock and down the back of one leg, sometimes all the way to the foot. Sitting through dinner becomes a chore, and a sneeze can make you wince. If that sounds familiar, you may be dealing with sciatica, one of the most common reasons adults in Boynton Beach and across Palm Beach County end up asking a doctor about back and leg pain.
In brief
- Sciatica is pain that follows the sciatic nerve from the lower back down one leg, usually caused by pressure on a nerve root.
- Many cases ease within weeks with staying active, gentle movement and physical therapy.
- Loss of bladder or bowel control, numbness in the groin area or a leg that is getting weaker needs care right away.
What sciatica actually is
Sciatica is not a disease on its own. It is a name for a pattern of symptoms. The sciatic nerve is the longest nerve in the body. It forms from nerve roots in the lower spine, runs through the buttock and travels down the back of each leg. When something presses on or irritates one of those roots, pain can travel along the nerve’s path.
That is why the leg can hurt more than the back. The problem sits near the spine, but the nerve carries the signal far away from it. Most of the time, sciatica affects only one side of the body.
Common causes
- A herniated or bulging disc. The soft cushions between the vertebrae can push outward and press on a nearby nerve root. This is the most common cause.
- Spinal stenosis. A narrowing of the space around the nerves, more common as people get older.
- Bone spurs. Overgrowths of bone linked to wear and tear in the spine.
- Less common causes. A slipped vertebra, an injury such as a fall or car accident, and, rarely, a growth pressing on the nerve.
Things that raise the odds include age, long hours of sitting, carrying extra weight, jobs that involve heavy lifting or twisting, and diabetes, which can affect nerves.
Sciatica symptoms to recognize
Sciatica can feel different from person to person, but the classic signs are fairly consistent:
- Pain that starts in the lower back or buttock and travels down the back or side of one leg
- A burning, sharp or electric feeling rather than a dull muscle ache
- Numbness, tingling or a “pins and needles” feeling in the leg or foot
- Weakness in the leg or foot, such as trouble lifting the toes
- Pain that gets worse with sitting, coughing, sneezing or bending forward
A pulled muscle in the back usually stays in the back. When the pain travels below the knee, or comes with numbness and tingling, a nerve is more likely involved. A doctor can tell the difference with a careful history and a hands-on exam, including simple checks of strength, reflexes and sensation.

When sciatica is an emergency
Most sciatica is painful but not dangerous. A few warning signs are different and should not wait for a regular appointment. Call 911 or get emergency care if you have:
- New loss of control of your bladder or bowels, or trouble starting to urinate
- Numbness in the groin, inner thighs or the area you would sit on a saddle
- Weakness in a leg that is getting worse, or both legs affected at once
- Severe back and leg pain after a fall, car accident or other injury
The first two can point to a rare but serious condition in which nerves at the base of the spine are badly compressed. Fast treatment matters. Fever along with back pain, or a history of cancer, are also reasons to be seen promptly.
What usually helps
The encouraging news is that many people with sciatica feel much better within a few weeks, often without surgery. Mainstream care tends to start simple:
Keep moving, gently
Long bed rest used to be common advice. Today, doctors generally encourage staying as active as you comfortably can. Short walks, changing positions often and avoiding long stretches in a chair or car can all help.
Heat, cold and over-the-counter relief
Some people find ice helpful in the first days and heat after that. Over-the-counter pain relievers can take the edge off for many adults, but they are not right for everyone, especially people with kidney problems, stomach ulcers, heart disease or those on blood thinners. Ask your doctor what is safe for you.
Physical therapy
A physical therapist can teach stretches and strengthening exercises for the back, hips and core, and show you how to sit, lift and move in ways that take pressure off the nerve. This is often the backbone of recovery and helps lower the chance of the pain coming back.
Imaging and specialist care, when needed
Many people do not need an MRI right away. Imaging becomes more useful when symptoms are severe, are not improving after several weeks, or come with warning signs. An MRI can show discs and nerves in detail. If conservative care is not enough, a doctor may discuss prescription medicines, spinal injections or, for some patients, a surgical opinion.
The usual path vs. having your own doctor
Sciatica is a good example of how much the path to care can shape the experience.
The usual way: A Delray Beach man wakes up on a Monday with pain shooting down his leg. His primary care office has no openings for two weeks, so he goes to urgent care, gets a prescription and a note to “follow up.” He then waits for an imaging appointment at one location, a physical therapy evaluation at another, and a specialist visit weeks out, repeating his story at every stop.
With your own concierge doctor: He texts his doctor that morning and is seen the same or next day, without a long wait in the lobby. If imaging is needed, MRI and X-ray are in the same building, and the physical therapy center is on site, so a plan can start quickly. If a specialist is needed, Wave normally gets patients in the same day, with records sent ahead and results reviewed together afterward.
Another example: a Boca Raton woman with diabetes notices tingling in her foot along with back pain. Instead of guessing whether it is her nerves, her blood sugar or her spine, she can call her doctor 24/7, weekends included, and talk through it with someone who already knows her history and her medication list.
Lowering the chances of a flare-up
Not every case can be prevented, but these habits support a healthier back:
- Get up and move every 30 to 60 minutes when sitting for long periods
- Lift with your legs, keep loads close to your body and avoid twisting while lifting
- Keep up core and hip strength with exercises a professional has shown you
- Stay active with walking, swimming or other low-impact movement
- Work toward a healthy weight and keep conditions like diabetes well managed

The bottom line
Sciatica can be intensely painful, but for most people it is manageable and improves with time, movement and the right guidance. Know the warning signs that need emergency care, and do not push through weeks of worsening pain, numbness or weakness on your own. Getting a clear answer early, with imaging and therapy close at hand when you need them, can make recovery faster and far less frustrating.
