Common causes of pain in the big toe include gout, a bunion, a claw toe, an ingrown toenail and a turf toe, according to WebMD. Osteoarthritis of the big toe is another common cause of pain in the big toe, notes Healthline. Keep Learning.
Bunions may or may not cause symptoms. A frequent symptom is foot pain in the involved area when walking or wearing shoes; rest relieves this pain. A bunion causes enlargement of the base of the big toe and is usually associated with positioning of the big toe toward the smaller toes. Shoe pressure in this area can cause interment pain while the development of arthritis in more severe bunions can lead to chronic pain. Bunions that cause marked pain are often associated with swelling of the soft tissues, redness, and local tenderness. It is important to note that, in postpubertal men and postmenopausal women, pain at the base of the big toe can be caused by gout and gouty arthritis that is similar to the pain caused by bunions.
