I have been running a lot recently but few days ago starting experiencing some pain especially near the arch of my right feet.

My mileage is between 20-30KM per week running 4 times per week.

It really hinders me from able to walk properly due to the pain. Did try to put on an ankle brace which wraps around the feet but it makes the pain even worse.

Any of you runners had this similar experience before? And how do you treat it.
