Annoying calf injury

Hi all.Im a field game player with a right calf injury,which has been present for approx 1 month.I do not remember the specific incident but recall being slightly sore afetr training one morning,and i continued to train on it for approx 1 week after that. After that i discontinued and havent been training since. The strange thing is, the pain seems to be constantly moving in the calf, it started behind the knee,moved to the musculotendinious junction,then the lateral aspect of the calf and now it’s behind the knee again!any sugestions? Ive been treating it with u/s,massage anti-inflammatory cream
