Stress Fracture: A common cause of persistent pain after an injury, especially if the patient has resumed activity without adequate rest. Stress fractures may not be immediately apparent on initial X-rays, making them a likely consideration in cases of prolonged pain.

Turf Toe: An injury to the ligaments around the big toe joint, which can cause pain that persists for months if not properly treated.
Toe Sprain: Similar to ankle sprains, toe sprains can cause lingering pain, especially if the injury was severe or if the patient has returned to activity too quickly.
Sesamoiditis: Inflammation of the tendons around the sesamoid bones under the first metatarsal bone, which can be caused by overuse or a direct blow to the area.

Osteomyelitis: A bone infection that can occur after an injury, especially if the skin was broken. It's crucial to diagnose and treat osteomyelitis promptly to prevent serious complications.
Compartment Syndrome: A condition where pressure within the muscles builds to dangerous levels, which can occur after an injury. It's a medical emergency that requires immediate attention.
Deep Vein Thrombosis (DVT): Although less common in the toes, DVT can occur in the legs and can be life-threatening if a clot breaks loose and travels to the lungs.

Gout: A form of arthritis that can cause sudden, severe attacks of pain in the toes, though it's less commonly associated with trauma.
Pseudogout: Similar to gout, pseudogout is a form of arthritis that can cause sudden, severe pain, but it's even less commonly linked to injury.
Complex Regional Pain Syndrome (CRPS): A chronic pain condition that can occur after an injury, characterized by intense burning or aching pain in the affected limb.
