Groin pain is very common in athletes and cricket players. Yes it is most commonly due to muscular or ligaments injury. Sincere request plz get an x-ray of the hip just to make sure no bony involvement like femoral neck stress fractures or changes in the head of femur. Very rarely labrum of hip can be involved which needs an MRI. I am not scaring you but giving you some information bcoz I see sports injuries with above conditions who do vigorous training exercises. Do not just blindly take painkillers

Please visit your nearest orthopedic doctor for further examination and  treatment . Depending on how much pain you are having and movement of your hip you will be treated further. Till then,  refrain from strenuous activity
