L04.3

Clinical Causes: Bacterial infections, such as Staphylococcus or Streptococcus bacteria, entering through cuts or wounds near the hip or leg Spread of infections from nearby skin or soft tissue infections Localized abscesses that extend to lymph nodes Infections stemming from other areas of the body reaching the lymph nodes via the lymphatic system Less commonly, fungal infections or parasitic infestations

Key Symptoms: Swelling or enlarged lymph nodes around the groin or hip area Tenderness or pain, especially when touching or moving the affected limb Redness and warmth over the affected lymph nodes Fever and chills if the infection is systemic Possible skin discoloration or ulceration if the underlying infection progresses Limited movement or discomfort in the hip or lower limb

Diagnosis Path: Physical assessment to check for swollen lymph nodes, redness, and warmth Blood tests to identify signs of infection and elevated white blood cell count Imaging studies such as ultrasound to visualize lymph nodes and surrounding tissues Fine needle aspiration or biopsy, in some cases, to identify the infectious agents or rule out other conditions Culture tests if an abscess or skin wound is present, to identify the causative bacteria

Treatment Protocols: Antibiotic therapy tailored to the suspected or identified infectious agent Pain relief medications such as NSAIDs to reduce discomfort and inflammation Rest and elevation of the affected limb to minimize swelling Warm compresses may be recommended to promote drainage and comfort Drainage procedures if abscess formation occurs Addressing underlying causes, such as wound care for skin infections Further medical intervention if the infection persists or worsens
