I am a 32 year old male who recently started having pain between the second and third metatarsals for no apparent reason. I run avidly without any trouble. Pain is constant and is decreasing however I have pain with plantarflexion of the toes to endrange and dorsiflexion of the toes to endrange. There is an area of swelling about the size of a silver dollar. this has decreased since the second day. I have tried everything for this and I am afraid to start running again as I am not pain free. How do I know when to go to the doctor and have some imaging taken.
