As you are an athlete such sort of pain can be due to micro fracture
or stress fractures
sustained due to repeated stress on ankle while playing.
Kindly get an Xray done first of all and get it evaluated by an orthopedician.
Take a week or two off from your gaming schedule. Try taking as much rest as possible.
An anti inflammatory medication like Nucoxia will help.
If Xray does not substantiate anything then an MRI
required to reach to a diagnosis.
