Hi Dear , As per your query you have extreme pain and stiffness in foot post an injury . Well the symptoms you mention in query can occur due to may reason like fracture in foot it can be minor like green stick or hair line fracture or major fracture , tearing of ligament or injury to soft tissue . But it seems to me that probaably there is no major fracture . I would suggest you to keep your foot in hot water tub or bucket with one spoon salt mix in it , take ibuprofen or acetaminophen for pain and swelling and keep it elevated while sleeping . If condition doesn t get better or get worse then consult orthopedic surgeon . Doctor will chest the movements , order x-ray orsometimes CT scan . Doctor may give splint , plaster and prescribe muscle relaxant along with multivitamine like vitamin d . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
