Differential Diagnosis for 17 Year Old Female with Back Pain, 5 Weeks Pregnant
- Single Most Likely Diagnosis
- Musculoskeletal back pain: This is the most common cause of back pain in pregnant women, especially in the early stages of pregnancy. The physical changes and strain on the back muscles during pregnancy can lead to musculoskeletal pain.
- Other Likely Diagnoses
- Urinary tract infection (UTI): UTIs are common during pregnancy due to physiological changes that can predispose women to infection. Back pain can be a symptom of a UTI, especially if it is a kidney infection (pyelonephritis).
- Pregnancy-related back pain due to ligamentous laxity: The hormone relaxin increases during pregnancy, causing ligaments to relax and potentially leading to back pain due to instability of the spinal joints.
- Do Not Miss Diagnoses
- Ectopic pregnancy: Although less likely, ectopic pregnancy is a life-threatening condition that requires immediate attention. Back pain can be a symptom, especially if the ectopic pregnancy is ruptured.
- Pulmonary embolism: Pregnancy increases the risk of blood clots and pulmonary embolism. Back pain can be a presenting symptom if the embolism is located in the lungs and is causing referred pain to the back.
- Pre-eclampsia: This condition can cause back pain, among other symptoms like high blood pressure and protein in the urine. It is a serious condition that can lead to complications for both the mother and the fetus if not promptly treated.
- Rare Diagnoses
- Spinal epidural abscess: A rare but serious condition that can cause back pain, fever, and neurological deficits. It requires prompt diagnosis and treatment to prevent long-term damage.
- Osteoporotic vertebral fracture: Although rare in young pregnant women, osteoporosis can be a cause of back pain, especially if there is a history of osteoporosis or prolonged use of corticosteroids.
