What it is
The pubic symphysis is the small joint where the two halves of your pelvis meet at the front. Osteitis pubis means the bone on either side of that joint has become irritated and stressed from repeated heavy loading.
It is the rugby and football injury you may have heard called a 'chronic groin' that just will not settle. It is different from a pulled adductor (a muscle injury) and from a sports hernia (a soft-tissue tear of the abdominal wall), although all three can present in similar regions and can overlap.
How it feels
- Deep, aching pain in the centre of the groin, often pointing one finger to the pubic bone itself.
- Pain with kicking, sprinting, change of direction, sit-ups, and getting out of a car.
- Tenderness when you press on the pubic bone at the very front of the pelvis.
- Pain that may radiate into the adductors, lower abdomen, or scrotum/perineum.
- Stiffness in the morning that eases with light movement but flares again with running or kicking.
Common drivers
- Repetitive kicking, especially in 10s, full-backs, and goal-kickers.
- High volume of cutting and lateral loading (wingers, scrumhalves, sevens players).
- Restricted hip rotation or stiff thoracic spine, which transfers load through the pelvis.
- Weak deep abdominal and adductor control after previous groin injury.
- Sudden spikes in training load — a common pattern when returning from pre-season.
Why it is not just a 'tight groin'
The bone next to the joint develops oedema (a stress reaction). Surrounding tendons — adductor longus from below and rectus abdominis from above — share an attachment around this region, so pain is rarely felt in one clean place. That is why imaging and a thorough exam matter.
