What it is, and its namesStrong evidence
The pubic symphysis is the joint at the front of the pelvis where the two pubic bones meet. The inner thigh muscles (the adductors) and the long tummy muscle (rectus abdominis) anchor close together over it. The Doha agreement defines pubic-related groin pain as tenderness of this joint and the bone right next to it, with no particular strength test that singles it out.
Osteitis pubis is the older name, and the one most people search for. The Doha agreement chose not to recommend it, along with sports hernia and athletic pubalgia, and a 2026 review keeps it only for one pattern of symptoms and scan changes within pubic-related groin pain. This guide uses both names.

What's going onEmerging evidence
It's thought to be a stress injury of the pubic bone and the tissues attached to it, from repeated pulling and shearing as you kick, sprint and cut. Magnetic resonance imaging (MRI) scans often show swelling inside the bone (bone marrow oedema), and samples of the bone have shown new bone forming. It isn't an infection, though an infection can look like it (see below).

Who gets itEmerging evidence
Footballers, Australian rules footballers, rugby and ice hockey players, and distance runners, mostly men in the studies. In a German professional youth academy, 14 of 189 players (7.4%) developed long-standing pubic-related groin pain in one season, at an average age of 16. In elite junior footballers, a lower training load before joining the squad went with developing it, which suggests building load gradually.

How it feels
Pain over or beside the middle of the pubic bone, on one or both sides, that builds with running, kicking, cutting, sit-ups and squeezing the knees together. It can spread to the inner thigh, the lower tummy, the area between the legs or the scrotum. When it's irritable, walking, stairs, rolling over in bed and coughing can hurt. Pressing on the pubic bone brings on the familiar pain.

How it overlaps with other groin painEmerging evidence
The Doha agreement describes four types of groin pain in athletes, by where they come from: the inner thigh muscles (adductor-related), the front of the hip (iliopsoas-related), the groin canal (inguinal-related, often called a sports hernia) and the pubic bone (pubic-related). Hip-related pain is a fifth, and an athlete can have more than one.
Pubic pain usually comes with something else. In 132 athletes with osteitis pubis on MRI, 90% also had a problem in an inner thigh tendon, and the side that hurt matched the tendon problem much better than the bone changes. In practice, a groin strain is tender on the inner thigh tendon, a sports hernia is tender in the groin canal above the crease and hurts with sit-ups and coughing, and hip-related pain pinches deep in the groin when you bend. Each has its own guide.

What scans show, and what they don'tStrong evidence
A scan can map other problems and rule things out, but a pubic bone finding on its own doesn't make the diagnosis, because the same changes are common in players without pain. Swelling that lingers on a scan shouldn't on its own stop a return once you're pain-free and playing well; a true stress fracture is the exception. In the academy group, a worse MRI grade did go with a longer return.
How common the changes are without pain:
- At the start of a season, 11 of 18 elite junior footballers without pain had moderate to severe swelling at the joint.
- In contact-sport teams, swelling was found in 53% of players with groin pain and 47% of players without it.
- Up to 71% of footballers without pain had some finding on MRI, though higher grades of swelling were more common with pain.
- On X-rays, thinning, new bone and hardening around the joint were as common in footballers without groin pain as in those with it.

In teenagersEmerging evidence
The growth plate on the pubic bone doesn't fully mature until the early to mid twenties. In 26 young footballers with groin pain from the inner thigh, computed tomography (CT) scans showed stress changes in it that weren't seen in players without pain. A teenager with lasting groin pain needs an assessment, and their load needs protecting rather than following an adult plan.

What not to miss: infection and stress fracturesEmerging evidence
An infected pubic joint is rare but serious. In a review of 100 cases, 74% had a fever, 68% pubic pain and 59% a painful or waddling walk. It followed incontinence surgery in 24%, sport (especially football) in 19%, pelvic cancer in 17% and injecting drugs in 15%, and it was often mistaken for osteitis pubis.
A stress fracture of the pubic bone or the top of the thigh bone, a hernia, and urinary, gynaecological and testicular problems are also on the Doha agreement's list of conditions not to miss, along with inflammatory arthritis of the spine.

How it usually goesEmerging evidence
Slowly. In one German academy, 14 young professional players on a rehab programme returned after 135 days on average (about 4.5 months): about 72 days with mild bone swelling on MRI, 148 with moderate and 251 with severe. That's one small group of teenagers, so the timings may not hold for adults or amateurs. In a trial of amateur footballers given intensive rehab, 42 of 44 were back within 4 months.
In 27 Australian professional footballers who rested from running sports for 12 weeks, 89% played the next season, but only 41% were free of symptoms at its start, rising to 67% by its end.
