Differential Diagnosis for Sudden Sharp Deep Left Groin Pain
Single Most Likely Diagnosis
- Muscle strain or pull: This is a common condition, especially in young and active individuals, where sudden movement or overexertion leads to muscle fiber tears. The symptoms of sharp pain, aggravation by movement, and inability to weight bear are consistent with this diagnosis.
Other Likely Diagnoses
- Groin hernia: Although less common in young women, a hernia could cause severe groin pain, especially if it becomes incarcerated or strangulated. The pain would be exacerbated by movement and coughing.
- Osteitis pubis: An inflammatory condition of the pubic bone and its surrounding structures, often seen in athletes. It causes groin pain that worsens with activity.
- Stress fracture: A small crack in a bone, often due to overuse or repetitive stress. It could cause severe pain in the groin area, especially with weight-bearing activities.
Do Not Miss Diagnoses
- Hip fracture: Although less likely in a young, well individual, a hip fracture (such as a femoral neck fracture) could present with severe groin pain and an inability to weight bear. Missing this diagnosis could lead to significant morbidity.
- Ovarian torsion: A gynecological emergency where the ovary twists around its ligaments, cutting off blood supply. It causes severe, sudden pain and requires immediate medical attention.
- Appendicitis (if the appendix is located in the pelvic area): Although the pain typically starts near the navel and then moves, in some cases, especially if the appendix is retrocecal, the initial pain could be felt in the groin area.
Rare Diagnoses
- Avascular necrosis of the femoral head: A condition where the blood supply to the femoral head is disrupted, leading to bone death. It could cause groin pain but is less common in young, healthy individuals without risk factors.
- Psoas abscess: A collection of pus in the psoas muscle, which could cause severe groin pain. It's more common in individuals with underlying conditions like spinal infections or Crohn's disease.
- Iliopsoas bursitis: Inflammation of the bursa that reduces friction between the iliopsoas muscle and the pelvis or femur. It could cause groin pain but is less common and often associated with specific activities or conditions.
