You might have injury
to Right knee which is continuously painful means something wrong.
So take advice of nearby Orthopedics for Ur injury.
but Some part of Pain occurring during movement.
ask Orthopedics for X-ray to rule out any minor crack.
Otherwise take Pain killer Medicine & wait to heal by naturally.
In My opinion consult Orthopedics.
Take care. Get well soon.
