Differential Diagnosis for Right Sided Redness and Inguinal Pain

  • Single Most Likely Diagnosis
    • Inguinal hernia: This condition is characterized by a protrusion of abdominal contents through a weakness in the inguinal canal, often presenting with inguinal pain and redness, especially if the hernia becomes incarcerated or strangulated.
  • Other Likely Diagnoses
    • Epididymitis: Inflammation of the epididymis, usually due to bacterial infection, can cause pain and redness in the inguinal area, particularly if the infection spreads to involve the surrounding tissues.
    • Inguinal lymphadenitis: Inflammation of the lymph nodes in the inguinal region can result from infection or other causes, leading to pain and redness.
    • Varicocele: Enlargement of the veins within the scrotum, similar to varicose veins, can cause discomfort and a feeling of heaviness, which might be accompanied by redness if there's associated inflammation.
  • Do Not Miss Diagnoses
    • Testicular torsion: A medical emergency where the spermatic cord becomes twisted, cutting off the blood supply to the testicle. It presents with severe pain and swelling but can also cause redness and might initially be mistaken for other less urgent conditions.
    • Necrotizing fasciitis: A severe infection of the skin and subcutaneous tissues that can quickly progress and is life-threatening. Early signs can include redness, pain, and swelling, making it crucial not to miss.
    • Appendicitis (if the appendix is located in a retrocecal position): Although appendicitis typically presents with abdominal pain, a retrocecal appendix can cause pain that is referred to the inguinal area, and if perforation occurs, it could lead to localized redness and inflammation.
  • Rare Diagnoses
    • Psoas abscess: An abscess of the psoas muscle can cause pain that radiates to the inguinal area, along with systemic signs of infection. Redness might be less prominent but could be present if the abscess extends to involve the skin.
    • Osteitis pubis: Inflammation of the pubic bone and its surrounding structures, often seen in athletes, can cause inguinal pain and might be accompanied by redness if there's significant inflammation or infection.
