Your feet and lower limb will need to be examined to find the cause of the pain and swelling. It could be due to a local problem or a nerve compression somewhere along the lower back for along the course of the nerves. Other causes of feet swelling like dilated veins,
kidney or heart related causes all so need to be ruled out. Some investigations like X rays and blood investigations may need to be done. See your nearest orthopaedic surgeon for the same.
