Has sitting through a long meeting, driving for extended periods or going for your usual walk suddenly brought on hip pain that was not there before? At first, it may be easy to brush it off as overuse or a minor strain. But when the sensation lingers, or quietly worsens over time, it can start to interfere with daily routines in ways that are hard to ignore. For many people, this is how hip impingement, also known as femoroacetabular impingement (FAI), begins to make itself known.
Hip impingement occurs when the bones of the hip joint do not fit together as smoothly as they should. Over time, this abnormal contact can irritate the cartilage and surrounding tissue, leading to pain and restricted movement. While symptoms often develop progressively, recognising the warning signs early and knowing when discomfort warrants assessment can make a meaningful difference to long-term joint health.
The signs of hip impingement vary in severity and often progress gradually as joint irritation increases. These can include:
One of the most noticeable signs of hip impingement is persistent pain in the joint that develops over time. This discomfort is often felt deep in the groin or at the front of the hip and may worsen during activities that involve bending or rotation. Many people first notice hip joint pain while sitting, particularly during long meetings, extended drives or desk work. As the condition advances, hip pain while walking may also become more apparent, especially after covering longer distances or moving uphill.
Stiffness in the hip joint is another warning sign, particularly after periods of rest. You may feel tightness when standing up after sitting or when getting out of bed in the morning. This stiffness can make the first few movements feel awkward or restricted before the joint gradually loosens. When stiffness is paired with recurring hip pain, it often signals underlying irritation within the joint rather than simple muscle fatigue.
Have you ever noticed a clicking or popping sound in your hip when you stand up from a chair, turn quickly or walk after sitting for a while? While joint noises are not always a cause for concern, repeated clicking accompanied by discomfort may indicate that the cartilage or labrum is being affected by abnormal contact within the joint.
As irritation within the hip persists, range of motion may decrease. This is often noticed during hip rotation, when standing up from a seated position or when changing direction while walking. Over time, everyday actions such as bending forward, sitting cross-legged or climbing stairs may become more challenging.

FAI can affect the hip joint in different ways, and understanding the type you have can explain your symptoms and guide treatment options. Below, we break down the most common types to give you a clearer picture of what may be happening in your hip.
Cam impingement occurs when the femoral head is not perfectly round. This irregular shape can rub against the hip socket during movement, gradually damaging cartilage. It is most commonly seen in younger, active individuals and may first show up as hip pain while walking or stiffness during activity.
Pincer impingement develops when the hip socket covers too much of the femoral head. This causes the labrum to become pinched during movement, leading to discomfort and a reduced range of motion. Activities such as bending forward, twisting or pivoting can trigger this catching or pinching sensation in the joint.
Many people experience a combination of both cam and pincer changes. Mixed impingement often results in more pronounced symptoms and may progress more quickly without appropriate care.
Managing FAI usually involves a mix of non-surgical strategies and, in more severe cases, surgical intervention. The best approach depends on the severity of your symptoms and how much the joint is affected.
Many people find relief from FAI through conservative treatments that aim to reduce pain, improve flexibility and support the hip joint without going under the knife.
When conservative care is insufficient, surgery may be recommended to correct structural issues within the hip.
If hip discomfort persists beyond a few weeks, continues to worsen, or begins to interfere with everyday activities such as walking, sitting, or bending, it may be time to seek professional assessment. Recurring pain that does not improve with rest, stiffness that limits movement, or clicking sensations accompanied by discomfort can all signal ongoing joint irritation. Early evaluation is particularly important if symptoms are affecting your mobility or quality of life, as timely care can help reduce further joint damage and support long-term hip health.
Staying mobile starts with understanding why the hip is hurting in the first place. With appropriate assessment, treatment can be aligned with your activity demands and long-term goals, whether that is conservative management or surgery when required. The focus is preserving range of motion, easing pain, and supporting everyday movement.
