Differential Diagnosis for Back Pain near Buttock Area

Single most likely diagnosis

  • Piriformis syndrome: This condition is characterized by pain in the buttock area, which is exacerbated by sitting. The piriformis muscle runs from the base of the spine to the thighbone, and when it compresses the sciatic nerve, it can cause pain. Given the patient's job as a taxi driver, which involves prolonged sitting, this diagnosis is highly plausible.

Other Likely diagnoses

  • Sciatica: This is a common condition that causes pain in the lower back and buttock area, often radiating down the leg. It can be caused by a herniated disk, bone spur, or other factors that compress the sciatic nerve. The patient's symptoms and occupation make this a likely consideration.
  • Coccydynia: This condition refers to pain in the tailbone area, which can be exacerbated by sitting. Although the pain is typically more localized to the coccyx, it could potentially radiate to the buttock area.
  • Sacroiliac joint dysfunction: This condition occurs when the sacroiliac joint, which connects the sacrum and ilium bones, becomes inflamed or irritated. It can cause pain in the lower back and buttock area, especially when sitting.

Do Not Miss diagnoses

  • Cauda equina syndrome: This is a serious condition that occurs when the nerves in the spinal canal are compressed, causing pain, numbness, and weakness in the legs. It is a medical emergency that requires prompt attention.
  • Spinal infection or abscess: Infections such as osteomyelitis or discitis can cause severe back pain, and if left untreated, can lead to serious complications.
  • Tumor or cancer: Although rare, tumors or cancer in the spine or pelvis can cause back pain, and it is essential to rule out these possibilities, especially if the pain is persistent and worsening.

Rare diagnoses

  • Ischiogluteal bursitis: This is an inflammation of the bursa that separates the ischial tuberosity and the gluteus maximus muscle. It can cause pain in the buttock area, especially when sitting.
  • Gluteal tendinopathy: This condition refers to inflammation or degeneration of the tendons that attach to the gluteus muscles. It can cause pain in the buttock area, especially when sitting or climbing stairs.
