## Overview Swelling in the femoral triangle (groin region) can result from hematoma, seroma, abscess, lymphadenopathy, or soft-tissue injury. It produces visible enlargement, heat, pain, and hind-limb lameness or reluctance to move the limb freely. ## Causes Trauma, injection-site reaction, infection, or vascular injury. ## Diagnosis Palpation, ultrasound, and aspiration if fluid is present. Bloodwork if systemic illness is suspected. ## Treatment Depends on cause: rest and anti-inflammatories for hematoma; drainage and antibiotics for abscess; surgical exploration for severe cases. ## Recovery and Prognosis Generally good once the underlying cause is addressed. ## Prevention Careful injection technique and trauma avoidance.
