Hammer Toe: This condition is characterized by a deformity of the toe where it curls downward, often due to imbalance in the muscles, tendons, or ligaments that normally hold the toe straight. It's common in women, especially those who wear high heels or poorly fitting shoes, which can exacerbate the condition.

Claw Toe: Similar to hammer toe, but it affects the entire toe, causing it to curl under. This condition can also be due to poorly fitting shoes or muscle imbalance.
Morton's Neuroma: Although primarily causing pain between the toes, Morton's neuroma can lead to changes in gait or toe positioning as the individual tries to avoid pain, potentially causing toes to overlap or curl.
Overlapping Toes: A condition where one toe overlaps another, often due to congenital deformity, poorly fitting shoes, or muscle imbalances.

Diabetic Neuropathy: Although less likely in a 25-year-old without a known history of diabetes, if present, it could lead to muscle weakness and imbalance causing toe deformities. Missing this diagnosis could lead to further complications if the underlying diabetes is not managed.
Peripheral Artery Disease (PAD): Reduced blood flow to the feet can cause pain and lead to changes in gait or toe positioning. While rare in young individuals, it's crucial not to miss this diagnosis due to its implications for cardiovascular health.
Neurological Disorders (e.g., Charcot-Marie-Tooth Disease): Certain neurological conditions can cause muscle weakness and atrophy leading to foot deformities, including curled toes. Early diagnosis is crucial for managing these conditions.

Arthrogryposis: A congenital condition that can cause curled toes among other deformities, due to muscle and joint abnormalities.
Freiberg's Disease: A rare condition that affects the metatarsal bones in the foot, potentially causing pain and changes in toe alignment.
Psoriatic Arthritis: Although more commonly associated with other symptoms, psoriatic arthritis can cause toe deformities, including curling, in severe cases.
