Hello and welcome to HCM
The
injury to your foot could have caused damage to the
soft tissue of your foot.
X-ray picks up only the bony lesions like
fracture.
However, soft tissue injuries are not picked up a X-ray.
Soft tissue includes muscles, ligaments, tendons, blood vessels and nerves.
Soft tissue injuries produce a dull, chronic and episodic type of pain.
The symptoms that you have mentioned appears to be most probably a ligament tear.
The tear is of low grade as the pain is not very severe and there is minimal problem in walking.
Give some hot formentation to the foot, use an ankle cap and use a muscle relaxant-
serratiopeptidase preparation and a pain killer whenever required.
If the symptoms do not dessappear in few days please visit an orthopedician.
Thanks and take care
