Differential Diagnosis
- Single Most Likely Diagnosis
- Migraines: The patient's symptoms of intense headaches starting in the occipital region and moving to the frontal area, accompanied by nausea, and relieved by quiet, darkness, and ice application, are classic for migraines. The history of optical migraines with visual disturbances such as zigzag lines and bars further supports this diagnosis.
- Other Likely Diagnoses
- Tension Headaches: The patient's description of waking up with headaches that worsen upon movement could also suggest tension headaches, possibly exacerbated by her chronic back issues.
- Hypertension-related Headaches: Given her recent history of high blood pressure, it's possible that some of her headaches are related to blood pressure fluctuations.
- Irritable Bowel Syndrome (IBS): Her gastrointestinal symptoms of bloating, sensation of food getting stuck, and suspected gluten sensitivity are consistent with IBS.
- Do Not Miss Diagnoses
- Subarachnoid Hemorrhage or Other Intracranial Bleeds: Although less likely given the recurrent nature of her headaches, it's crucial to consider the possibility of an intracranial bleed, especially with the sudden onset of severe headache.
- Temporal Arteritis: This condition, more common in older adults, can cause headaches, visual disturbances, and is associated with elevated erythrocyte sedimentation rate (ESR). Given her age and symptoms, although not explicitly mentioned, this should be considered.
- Kidney Disease or Kidney Stone: Her history of kidney stones and an atrophic left kidney necessitates consideration of renal causes for her headaches, including possible kidney disease or another stone.
- Rare Diagnoses
- Chiari Malformation: This rare structural defect in the cerebellum could cause headaches, especially those worsened by movement, and might be considered given her complex symptomatology.
- Idiopathic Intracranial Hypertension (IIH): Characterized by increased intracranial pressure without a detectable cause, IIH can lead to headaches, visual disturbances, and is often associated with obesity and female gender. Although her symptoms don't perfectly align, it remains a rare possibility.
