This condition occurs at the front inside of the shin bone and results in pain at the start of exercise, fading away as the session progresses and returning when the activity ceases. Pain is usually felt when the toes or foot are bent downwards. There may also be lumps or bumps felt over the area. Treatment involves rest to allow the injury to heal. Icing and anti-inflammatories may also be helpful. Common reasons this condition can occur can be the foot stance you have such as overpronating (sole of the foot turns outwards) or oversupinating ( sole of the foot turns inwards) causing the foot to not absorb shock during running.
