Differential Diagnosis for Bilateral Adductor Magnus Pain
- Single most likely diagnosis
- Delayed Onset Muscle Soreness (DOMS): This condition is characterized by muscle soreness that develops 24-48 hours after intense or unfamiliar exercise, which matches the patient's symptoms. The fact that it happens the day after working out and has been recurring for a couple of years supports this diagnosis.
- Other Likely diagnoses
- Adductor Strain: Given the location of the pain and the patient's history of working out, an adductor strain is a plausible diagnosis. However, the fact that it's bilateral and happens consistently after working out might lean more towards an overuse or repetitive strain issue rather than an acute injury.
- Weak Hip Abductors: The patient's form during exercises, such as stepping down from a height with the knee angled medially, suggests weakness in the hip abductors. This weakness can lead to altered biomechanics, putting additional stress on the adductor magnus muscles, potentially causing pain.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Stress Fracture: Although the patient has no known hip pathology, a stress fracture in the femur or pelvis could cause pain in the adductor region, especially if it's related to overuse or repetitive stress from working out. Missing this diagnosis could lead to further complications if not addressed.
- Osteonecrosis: This condition, also known as avascular necrosis, could potentially cause pain in the hip area, including the adductor magnus, especially if there's an issue with blood supply to the bone. It's less likely but critical to consider due to its serious implications.
- Rare diagnoses
- Chronic Exertional Compartment Syndrome: This condition involves increased pressure within a muscle compartment, leading to pain during exercise. It's less common but could be considered if the pain is severe and specifically related to exercise intensity and duration.
- Adductor Magnus Tendinopathy: Tendinopathy of the adductor magnus tendon could cause chronic pain in the region, especially with activities that stress the tendon. This diagnosis might be less common but should be considered in the differential, especially if other causes are ruled out.
