The outer hip tendons: the commonest women's hip problem from mid-lifeStrong evidence
Pain over the bony point on the outside of the hip, sometimes down the outer thigh, is usually the tendons of the buttock muscles where they attach to the bone (greater trochanteric pain syndrome, often called hip bursitis). In 3,026 US adults aged 50 to 79, it affected one hip in 15.0% of women and 6.6% of men, and both hips in 8.5% and 1.9%, so women had about 3.4 times the odds; NHS inform says it is more common in women and in people aged 40 to 60. Among young, active US military personnel, women had about 5 times the rate of men.
It hurts to lie on that side, on stairs, standing on one leg, sitting with your legs crossed and getting your legs in or out of a car or bed. NHS inform lists a sudden rise in walking or activity, a fall onto the side of the hip, weak hip muscles, sitting or standing in one position for too long, being overweight and hormone changes among the things that can contribute, and it often goes with low back pain or arthritis of the hip or knee. A review suggests the tendons suffer most when they're squeezed against the bone as the thigh drifts across the body. It is often mistaken for back trouble: half of 273 people seen in one spine clinic had it, women more often than men.

The hip joint, a shallow socket and very flexible joints
Hip arthritis is felt in the groin, the front of the thigh or the buttock, worse walking and stiff after rest, usually from about 45, and the National Institute for Health and Care Excellence (NICE) diagnoses it without a scan at that age. The NHS says osteoarthritis is more common in women, and worldwide rates of osteoarthritis as a whole are higher in women, but in a meta-analysis the difference between the sexes was clear for the knee and hand, not for other joints such as the hip.
In younger women, a shallow hip socket (dysplasia) and very flexible joints are the causes most linked with being a woman. Dysplasia showed on X-rays of 3.4% of 4,151 Danish adults, with little difference between the sexes, but girls are at higher risk as babies, and mild dysplasia can first cause symptoms in adulthood. At one hip clinic, 77.9% of adults with dysplasia had very flexible joints, against 32.8% of those with other hip problems, and 70% of the people diagnosed with hypermobility disorders in Wales were women. The NHS says building muscle strength and fitness is the main treatment for joint hypermobility syndrome.

Pregnancy, the menopause and your bones
Pelvic girdle pain affects up to 1 in 5 pregnant women: pain at the pubic bone, across the low back, between the vagina and anus or into the thighs, worse walking, on stairs, standing on one leg, turning in bed and getting out of a car. It isn't harmful to your baby. Rarer causes of hip pain in pregnancy and after the birth include a temporary thinning of the hip bone late in pregnancy (transient osteoporosis), a labral tear after the birth, and a squeezed skin nerve on the outer thigh (meralgia paresthetica).
After the menopause, women lose bone quickly, so a fall can break the hip. In England in 2024, 69.0% of people who broke a hip were women, and the average age was 82.4; the national audit notes that women can develop osteoporosis after the menopause. A broken hip hurts in the hip, the upper leg and the groin, and you can't stand or put weight on the leg.

Pain from elsewhere
Problems in the lower back can be felt only in the buttocks, down the back of the legs and over the outside of the hip, and NHS inform says a hip problem can come from the back even when the back doesn't hurt. A femoral hernia, a small, grape-sized lump at the top of the thigh in the groin, mainly affects women over 50 and needs treating in hospital; other hernias can grow when you cough or strain. The pelvic organs can be felt in the lower tummy and groin, and rarely a hip joint is infected, which makes it hot, swollen and very painful, often with a high temperature.

When a scan or test helpsStrong evidence
Outer hip pain and hip arthritis are diagnosed by examination: NICE diagnoses osteoarthritis without imaging from 45 when activity brings on joint pain and morning stiffness lasts 30 minutes or less. Dysplasia in adults is confirmed with hip X-rays. After a fall, X-rays come first, and NICE offers a magnetic resonance imaging (MRI) scan if a broken hip is still suspected despite normal X-rays. A thinning of the hip bone in pregnancy shows on MRI. A hot, swollen joint needs urgent tests, including fluid taken from the joint. The LEAP trial used MRI to confirm outer hip pain for research, but everyday care doesn't need a scan.

How it usually goesEmerging evidence
Outer hip pain is slow: an NHS physiotherapy leaflet expects most people to improve over 8 to 12 weeks of the right exercise and changes, some taking up to a year, and NHS inform says it often takes 6 to 12 months of rehabilitation, with flare-ups along the way. In the LEAP trial, 51 of 66 people rated education plus exercise a success at 8 weeks, and 51 of 65 at a year. Hip arthritis tends to change slowly over years, and exercise eases the pain a little while it's kept up. Pelvic girdle pain usually gets better after the birth. Recovery from a broken hip takes weeks to months. No one can promise a timescale.
