hip pain ultrasound explained

Overview

An ultrasound scan of the hip uses sound waves to create pictures of the inside of your hip. It helps doctors see fluid, inflammation, or problems with the joint and nearby tissues, without using radiation.

Ultrasound for hip pain is a common test. It is often used when a doctor suspects problems with muscles, tendons, or fluid around the hip.

It can be used for people of all ages, from children to older adults. However, the reasons for hip pain and what the doctor looks for may differ by age.

Symptoms

Common symptoms

• Pain in the front, side, or back of the hip
• Stiffness or difficulty moving the hip
• Swelling or tenderness around the joint
• A feeling of catching or clicking inside the hip

Symptoms in children

• Limping or walking oddly
• Complaining of pain in the thigh or knee (this can be hip pain)
• Refusing to put weight on one leg
• Unexplained fever with hip pain

Symptoms in older adults

• Aching in the hip or groin that worsens with activity
• Pain at night or when getting out of a chair
• Stiffness in the morning
• Reduced ability to walk or do daily activities

Causes

Main causes

• Inflammation in the tendons or muscles around the hip (tendinitis)
• Fluid buildup (bursitis), especially on the outside of the hip
• Osteoarthritis, which is wear-and-tear of the joint cartilage
• Injury such as a strain or tear in ligaments or muscles
• In children, conditions like transient synovitis (temporary hip inflammation)

Risk factors

• Getting older
• Repeated hip movements or overuse in sports or work
• Being overweight
• Previous hip injury or surgery
• Certain inflammatory conditions like rheumatoid arthritis

When to see a doctor

See a doctor urgently if:

• Severe pain, especially after a fall
• Fever with hip pain
• Inability to move your hip or put weight on it
• Numbness or tingling in the leg

Book a routine appointment if:

• Hip pain that lasts more than a few weeks despite rest
• Pain that affects your daily activities, such as walking or climbing stairs
• Clicking, locking, or a feeling of instability in the hip
• Pain that is worse at night or in the morning

Diagnosis

A doctor will ask about your symptoms and examine your hip. If they need a closer look at the soft tissues or fluid around the joint, they may recommend an ultrasound scan. Ultrasound can show movement in real time and helps guide injections if needed.

Tests that may be done

• Ultrasound scan of the hip
• Physical examination
• Sometimes blood tests to check for infection or inflammation
• X-ray if the doctor needs to see the bone structure

What to expect at your appointment

You will lie on a bed and the sonographer will apply a clear gel on your skin. They will gently move a small probe over your hip. The scan is usually painless and takes about 15 to 30 minutes. There is no downtime, and you can go home right after.

Treatment

Treatment depends on the cause of your hip pain. Many cases improve with rest, gentle movement, physiotherapy, and simple pain-relief methods. Your doctor will work with you to create a plan.

Self-care at home

• Rest the hip, but avoid staying completely still for long periods — gentle motion helps
• Apply a soft cold pack for the first few days to reduce swelling
• Use a warm pack (heat) for muscle stiffness after the first few days
• Raise the leg on pillows when resting or sleeping
• Try gentle stretching and walking, as pain allows

Medical treatments

Medical treatment may include physiotherapy to strengthen the muscles around the hip. Some people benefit from an ultrasound-guided injection of a steroid medicine (a strong anti-inflammatory) into the painful area. Oral pain relievers and anti-inflammatory medicines may also be suggested. Always ask your doctor or pharmacist about the right choice for you.

When is surgery considered?

Surgery is rarely needed for hip pain. It may be considered for severe arthritis, a serious injury like a hip fracture, or in children for certain hip problems. Your doctor will explain if and when surgery is an option.

Living with this condition

Plan your day so that you take breaks before the pain becomes bad. Choose chairs with firm, supportive seats. When getting in and out of a car, slide your leg in and out instead of twisting. Use a walking stick on the opposite side of the painful hip to reduce pressure.

Lifestyle tips

• Keep moving with low-impact activities like swimming or cycling
• Avoid high-impact sports like running or jumping until pain improves
• Maintain a healthy weight to reduce stress on the hip
• Wear supportive, comfortable shoes

Diet and exercise

A balanced diet with plenty of vegetables, fruits, whole grains, and lean protein can support your overall health. If you are overweight, losing even a small amount can ease hip pain. Gentle exercise like walking, swimming, or gentle yoga can keep the hip joint moving and the muscles strong, as long as it does not cause sharp pain.

Mental health and emotional wellbeing

Ongoing hip pain can affect your mood, sleep, and confidence. It can make you feel frustrated or anxious. It is normal to feel this way. Talking to someone you trust, joining a support group, or speaking to a counsellor can help.

Prevention

Not all hip pain can be prevented, especially if it is due to ageing or injury. But you can reduce the risk of overuse injuries by warming up before exercise, strengthening your hip and core muscles, and listening to your body when it hurts.

Vaccines

Some hip infections are caused by bacteria. Keeping up to date with recommended vaccines, such as the flu vaccine, may reduce the risk of infections that could spread. But there is no specific vaccine for hip pain. Always ask your doctor for advice.

Screening programmes

There is no routine screening test for hip pain in healthy people. If you have a family history of hip problems or a known condition, your doctor may recommend regular check-ups.

Complications

If left untreated

• Untreated infection can spread and damage the joint permanently
• Severe or long-lasting hip pain can lead to muscle weakness, poor balance, and falls
• In children, untreated hip conditions like developmental dysplasia may lead to ongoing hip problems
• Untreated arthritis can make the joint increasingly stiff and difficult to move

Long-term outlook

Most causes of hip pain respond well to simple measures like rest, exercise, and physiotherapy. With the right help, most people get back to their usual activities. Even if a more serious cause is found, there are many effective ways to manage it. It is never too early or too late to seek help.
