If your big toe hurts when running, there are a couple of reasons this may be happening. Turf toe, or a sprain to the ligaments in the big toe, is one. If you use your toes to push off the ground when you run, but the toe sticks flat to the ground instead of rising up, you run the risk of overextending these ligaments. The injury and pain are sudden and can be severe.Another reason for toe pain is hallux rigidus. This is a type of arthritis that affects runners. It is a chronic condition that gets worse over time without treatment. In order to treat this condition, you might only need to change your footwear or use an orthotic device to provide proper support.To find out more information about toe conditions that cause pain call Dr. Mitchell Wachtel at (888) 616-2512 to schedule an appointment in one of three Massachusetts locations.
