Migraines with Aura: The patient's history of migraines, especially those triggered by sensitivity to light and associated with frontal head pressure, is consistent with migraines with aura. The symptoms of dizziness and blurred vision can be part of the aura phase or a consequence of the migraine itself. The patient's history of LASIK surgery and the onset of migraines post-surgery could be coincidental or related to the surgery, but the primary complaint aligns closely with migraine characteristics.

Tension Headaches: Given the patient's history of depression and anxiety, tension headaches could be a contributing factor to the patient's symptoms, especially considering the frontal location of the pain.
Post-LASIK Complications: Although less common, complications from LASIK surgery could potentially contribute to the patient's symptoms, including dry eye, which might exacerbate light sensitivity and contribute to headaches.
Musculoskeletal Pain: The new-onset rib pain, especially after engaging in HIT (High-Intensity Training) workouts, could be related to musculoskeletal strain or injury, which is a common occurrence after intense physical activity.

Temporal Arteritis: Although less likely in a 31-year-old, temporal arteritis (giant cell arteritis) can present with headaches, visual disturbances, and sensitivity to light. It's a condition that requires prompt diagnosis and treatment to prevent serious complications like blindness.
Multiple Sclerosis: This condition can present with a wide range of neurological symptoms, including vision problems, dizziness, and pain. While the patient's symptoms could be explained by other diagnoses, multiple sclerosis is a "do not miss" diagnosis due to its significant impact on quality of life and the importance of early treatment.
Intracranial Hypertension: Idiopathic intracranial hypertension (IIH) can cause symptoms similar to those experienced by the patient, including headaches, vision changes, and sensitivity to light. It's particularly important to consider in patients with a history of weight changes or other risk factors, though none are explicitly mentioned here.

Chiari Malformation: A structural defect in the cerebellum that can cause a range of neurological symptoms, including headaches, dizziness, and visual disturbances. It's a rare condition but one that could potentially explain the patient's symptoms, especially if there's an association with physical activity or certain positions.
Occipital Neuralgia: Involves the nerves that run from the base of the skull to the scalp and can cause pain, often described as sharp and stabbing, as well as other symptoms like sensitivity to light. It's less common but could be considered if other diagnoses are ruled out.
