why do the outsides of my feet hurt

I would suspect a stress fracture except that there was never any swelling, I was negative for the "tuning fork test," and the sore area seems too large to be a localized stress fracture. I have had a hard time finding information online about recurring subluxed cuboid, prevention, or other pain/injuries that might accompany this condition. Do you have any idea what might have happened to me?


Other info- I have newish, but not brand new shoes. I have no other injuries at this time for which I might have been overcompensating. I do tend to overpronate. When can I run again? Will I be able to complete a half marathon in February? - Deborah Answer: The initial pain that you experienced sounds like a cuboid subluxation, but could also be due to a stress fracture (5th or 4th metatarsal or less likely cuboid).


The peroneal tendon runs along the side of the foot and attaches to the base of the 5th metatarsal; injury of of the tendon could also cause pain in the outer aspect of the foot. The lack of response to manipulation with this injury may be due to an inaccurate diagnosis or an unstable cuboid - the reduction does not hold. Taping alone or taping with a felt pad may stabilize the cuboid.


It may take a little experimentation to determine the best taping method. The pain that is now present in the 4th metatarsal may be a stress fracture. Swelling is usually mild; pain may not be pinpoint but more diffuse, as you are experiencing. Other possible causes of pain in the forefoot include tendinitis, neuroma and inflammation of the metatarsal-toe joint (MTP joint).


X-rays should be performed initially; if pain persists and the diagnosis is in question, an MRI may be helpful. Your ability to train for and complete a half marathon in the near future is dependent upon the exact diagnosis and your response to treatment. Limping through a workout does nothing to improve your fitness and may result in a more serious injury. Good luck with the injury.
