Why Does Hip Pain Shoot Down Your Leg at Night?

Do not index

Hip pain that shoots down your leg at night may trace back to one of three places: an irritated nerve in the lower back, an inflamed bursa on the outer hip, or the hip joint itself. Where the pain travels and which position wakes you can help point to the source.

You settle into bed after a long day in Ft. Myers, and an hour later a line of pain runs from your hip toward your knee or even your foot. At Thrive Medical Centers, the first job is working out where that pain starts, so this guide walks through the three usual sources and the clues that separate them.

Why does nighttime make hip pain travel down the leg?

Night brings two changes: you stay in one position for hours, and you may lie directly on a sore hip. OrthoInfo says hip bursitis pain is typically worse at night and when lying on the affected hip, and MedlinePlus lists night as a time when sciatica pain may get worse.

Two different problems share that bedtime timing, so the pattern around the pain matters more than the clock. MedlinePlus notes that sciatica may also get worse after standing or sitting, when coughing or sneezing with a herniated disk, or when bending backward or walking with spinal stenosis. OrthoInfo describes bursitis pain that also flares when you get up from a chair after sitting for a while. The hip joint can add a third possibility, so one symptom alone rarely settles the question.

Could a pinched nerve in your lower back be causing the leg pain?

A pinched nerve in the lower back can send pain into the hip and leg. MedlinePlus describes sciatica as pain, weakness, numbness, or tingling in the leg from pressure on or damage to the sciatic nerve, which starts in the lower back.

The causes vary. MedlinePlus lists a herniated disk, spinal stenosis, piriformis syndrome (a pain disorder involving a narrow muscle in the buttocks), pelvic injury or fracture, tumors, and spondylolisthesis. It also says the pain most often occurs on one side and that sciatica is a symptom of a medical problem, not a condition by itself, so the underlying cause needs to be found. Pain that starts in the lower back or buttock and follows the back of the leg, with tingling or numbness, fits this group better than pain centered on the side of the hip. The practice’s lower back pain and sciatica page covers sciatica and the lower back care it offers.

Why does the outer hip hurt most when you roll onto your side?

Pain at the point of the hip that extends toward the outer thigh is the main symptom of trochanteric bursitis, an inflamed bursa over the bony point of the hip. OrthoInfo says the pain is typically worse at night, when lying on the affected hip, and when rising from a chair after sitting a while.

A bursa is a small, fluid-filled sac that cushions the space between bone and soft tissue. OrthoInfo lists lying on one side of your body for an extended period among the ways the point of the hip can be injured, along with falls, overuse, a tight IT band, and one leg being shorter than the other. It also lists spine problems such as scoliosis and arthritis of the lower spine, a reminder that the back and the hip often share the blame. Bursitis pain usually extends to the outside of the thigh, so pain that travels below the knee deserves a second look. MedlinePlus lists pain traveling down the legs below the knee, along with weakness or numbness in the buttocks, thigh, or leg, among reasons to contact a provider right away.

Can the hip joint itself cause pain that reaches the thigh and knee?

It can. Mayo Clinic says pain inside the hip joint tends to show up in the groin or inner hip. SingHealth adds that hip joint pain may also be felt at the side and front of the thigh, in the buttock, or down to the knee, which is called referred pain.

Osteoarthritis is one of the conditions Mayo Clinic lists among causes of hip pain. SingHealth notes that stiffness tends to be worse in the morning and eases with activity. It also advises seeking medical attention for constant hip pain, hip pain that wakes you from sleep, or pain with fever or loss of weight or appetite. The practice’s hip pain page adds that pain can be more intense when you lie down or change positions, and that mornings may bring stiffness.

Which clues help separate a nerve problem from a joint or bursa problem?

Location is the first clue. Mayo Clinic says groin or inner hip pain points to the joint, while pain on the outer hip, upper thigh, or outer buttock usually involves soft tissues such as bursal sacs. Nerve pain, by contrast, starts in the lower back and runs down the back of the leg.

Mayo Clinic also notes that hip pain can sometimes come from the lower back, so the hip is not always where the problem sits. At a visit to Thrive Medical Centers, the provider asks where the pain sits, which movements bother it, and whether it spreads into the lower back, buttock, or thigh. You may be guided through movements that test flexibility and joint function, and pain, popping, catching, or restriction in certain positions gives the provider more to work with. Depending on what the history and exam show, X-rays or an MRI may be considered. Before you come in, jot down which side you were lying on when the pain began and exactly where it traveled, since those details may help point toward one of the three sources.

When does night pain down the leg need a call this week or an emergency room?

If the pain also involves your back, Mayo Clinic advises emergency care for new bowel or bladder control problems, a fever, or trauma such as a bad fall or crash. Constant or intense pain that is worse at night belongs in its call-your-doctor group, so schedule a visit this week.

MedlinePlus adds more reasons to contact a provider right away: pain that is worse lying down or wakes you at night, severe pain that keeps you from getting comfortable, and loss of control of urine or stool. It also suggests a call when an episode lasts longer than 4 weeks. The Ft. Myers office is open Monday through Friday from 9 am to 4 pm, so pain that starts at 2 a.m. with none of the emergency signs can wait for a call to the front desk at (239) 460-8225 on the next business day.

The Short Version: Where It Travels, Which Position Triggers It, and When to Call

Three habits make night pain easier to sort out. First, note where the pain travels: groin or inner hip suggests the joint, outer hip suggests a bursa or other soft tissue, and the lower back and back of the leg suggest a nerve. Second, note the position: pain that flares when you lie on the sore hip fits bursitis, while pain that also changes with sitting, coughing, or walking fits a nerve source. Third, treat leg weakness, numbness, pain below the knee, new bladder or bowel changes, or fever as reasons to call promptly. Thrive Medical Centers can evaluate pain that keeps waking you.

Quick Answers About Night Pain From the Hip Down the Leg

Does nerve pain usually affect both legs?

Sciatica most often occurs on one side of the body, according to MedlinePlus. New bladder or bowel changes with it call for emergency care, per Mayo Clinic.

Does pain that wakes me up mean something serious?

Waking at night is not always serious, since bursitis and sciatica can both worsen after dark. Still, MedlinePlus and SingHealth both list pain that wakes you as a reason to call a provider.

Can hip bursitis cause pain below the knee?

OrthoInfo describes bursitis pain as centered at the point of the hip and usually extending to the outside of the thigh. Pain traveling below the knee is on MedlinePlus’s list of reasons to contact a provider right away.

Can a back problem cause pain only in the hip and leg?

It can. Mayo Clinic says hip pain can sometimes come from the lower back, and MedlinePlus notes sciatica may bring sharp pain in one part of the leg or hip with numbness elsewhere.

What should I bring to a visit for night pain?

Bring notes on which position wakes you, where the pain travels, and what eases it. Thrive Medical Centers uses details like these to decide what to evaluate next.
