Pain that hits both your pelvis and hips at the same time usually comes from one of a handful of common sources: a joint problem, muscle or tendon irritation, or an internal issue referring pain outward. The pelvis and hips share so much anatomy (bones, muscles, and nerves overlap extensively in this region) that a single problem can easily produce pain you feel in both areas. Sorting out what’s going on starts with paying attention to exactly where the pain is, what triggers it, and whether it came on gradually or suddenly.
Where You Feel It Narrows the List
Hip and pelvic pain gets categorized by location: anterior (front), lateral (side), or posterior (back). Front-of-hip pain that extends into the groin often points to something inside the joint itself, like cartilage damage or arthritis. Pain on the outer side of the hip is more commonly from soft tissue irritation, particularly the tendons and fluid-filled sacs around the bony prominence you can feel on the outside of your upper thigh. Pain in the back of the hip or deep in the buttock frequently involves the sacroiliac joint, the deep gluteal muscles, or the lower spine.
The tricky part is that problems inside the abdomen or pelvis, like ovarian cysts, hernias, or bladder issues, can masquerade as hip pain. If your pain comes with changes in urination, bowel habits, or menstrual patterns, that’s a strong signal the source may be internal rather than musculoskeletal.
Sacroiliac Joint Dysfunction
The sacroiliac (SI) joint sits where your lower spine connects to your pelvis, and it’s one of the most common culprits when both the hip and pelvis hurt at the same time. Pain from SI joint dysfunction is typically felt in a surprisingly small area, roughly 3 by 10 centimeters, just below the bony bump on the back of your pelvis. But it doesn’t stay put. It commonly radiates into the buttock, groin, back of the thigh, and sometimes down into the lower leg, which is why it’s easy to mistake for a hip problem or even sciatica.
SI joint pain tends to flare with activities that load one side of the pelvis unevenly: climbing stairs, standing on one leg, or transitioning from sitting to standing. Diagnosis involves a cluster of hands-on tests that stress the joint in different directions. If multiple tests reproduce your pain, the SI joint is the likely source. In some cases, a numbing injection into the joint confirms the diagnosis when the pain temporarily disappears.
Greater Trochanteric Pain Syndrome
If the pain is concentrated on the outer side of your hip, greater trochanteric pain syndrome (sometimes called hip bursitis) is a leading possibility. The condition involves inflammation of the bursa, a small cushioning sac that sits between the outer hip bone and the thick band of tissue running down the outside of your thigh. Repetitive stress, whether from running, walking long distances, or simply sitting for extended periods, is the usual trigger.
People with this condition describe pain across the lateral thigh and buttock that can radiate down the leg. It frequently intensifies when lying on the affected side, climbing stairs, or standing on one leg. Prolonged sitting and side-bending also make it worse. The pain can persist for weeks to years before someone seeks treatment, partly because it tends to wax and wane. You can often pinpoint the exact sore spot by pressing directly over the bony prominence on the outside of your hip.
Labral Tears
The labrum is a ring of cartilage that lines the rim of your hip socket, helping to keep the ball of the thigh bone seated properly. When it tears, whether from repetitive motion, a structural mismatch in the joint, or an injury, the hallmark is deep groin or front-of-hip pain accompanied by mechanical symptoms. Clicking is the most consistent one. You may also notice catching, locking, or a feeling that your hip gives way during certain movements.
Labral tears tend to produce pain during activities that involve rotating or flexing the hip deeply, like getting in and out of a car or squatting. The pain often builds gradually and can be hard to pin down at first because it feels deep inside the joint rather than on the surface.
Osteoarthritis
Hip osteoarthritis is one of the most straightforward explanations for combined hip and pelvic pain, especially if you’re over 50 or have a history of hip injuries. As the cartilage lining the hip joint wears down, the resulting inflammation and bone-on-bone friction cause a deep, aching pain that’s typically felt in the groin, front of the thigh, or buttock. Stiffness in the morning or after sitting is common, and range of motion gradually decreases over months or years. Because the hip joint sits deep within the pelvis, arthritis pain often feels like it belongs to both regions at once.
Pelvic Floor and Myofascial Pain
The muscles of the pelvic floor span the base of your pelvis like a hammock, and when they develop chronic tension or trigger points, the resulting pain can radiate into the hips, lower back, groin, and thighs. This type of pain is often described as a deep ache or pressure that’s hard to localize. It may worsen with prolonged sitting, stress, or certain physical activities.
Pelvic floor physical therapy has strong evidence behind it. In one study of patients diagnosed with myofascial pelvic pain, 63% reported significant improvement after a course of targeted physical therapy, with pain scores improving proportionally to the number of sessions completed. Three-quarters of those patients had started with pain rated 7 out of 10 or higher, so these weren’t mild cases.
Pregnancy-Related Pelvic Girdle Pain
If you’re pregnant, pain across the pelvis and hips has a very specific and common explanation. Your body begins producing the hormone relaxin as early as 10 weeks into pregnancy, loosening the ligaments that hold the pelvic bones together to prepare for delivery. This loosening can make the pelvis feel unstable, wobbly, or outright painful, particularly at the pubic symphysis joint at the front.
Symptoms range from mild discomfort at the front of the pelvis to sharp, shooting pain in the front or back that radiates into the lower abdomen, groin, and thighs. Some people experience tingling, burning, or throbbing sensations. The pain typically intensifies as pregnancy progresses and the baby gets heavier, putting more load on the loosened joints. Intense stabbing pain that makes walking extremely difficult may indicate symphysis pubis dysfunction, a more severe form of this loosening.
Endometriosis and Referred Nerve Pain
For people with endometriosis, hip and pelvic pain can stem from endometrial tissue growing near or into the nerves that pass through the pelvis. When tissue infiltrates the area around the sciatic nerve (typically at the sciatic notch), it produces pain in the posterior thigh that radiates down the leg, sometimes with muscle weakness or sensory changes. The hallmark clue is that this sciatica-like pain follows a cyclic pattern tied to menstruation, with progressively shorter pain-free windows between episodes.
Endometrial tissue can also affect the obturator nerve, which runs along the pelvic wall. This causes inner thigh pain, weakness when trying to squeeze the legs together, and sometimes difficulty walking. These nerve-related symptoms can occur even without other obvious signs of endometriosis elsewhere in the pelvis, which makes them easy to miss.
When the Pain Needs Urgent Attention
Most hip and pelvic pain develops gradually and responds to rest, physical therapy, or activity modification. But certain situations call for immediate evaluation. If your pain followed a fall, car accident, or other trauma, or if you can’t move your hip or bear weight on that leg, you should be seen in an emergency department to rule out a fracture. Pain that’s constant, intense enough to disrupt your daily routine, or accompanied by unexplained weight loss or fever also warrants a prompt visit to your healthcare provider, since these patterns can signal infections, inflammatory conditions, or other systemic problems that need timely diagnosis.
