Patient: I recently found an egg-sized sac in the left side of the testicle, which feels soft to the touch and can be returned to the abdominal cavity, is it an inguinal hernia? Thank you! Ma Xiaopeng: From your description, it may be a hernia. Don’t worry, the child is only two months old now, so you can continue to observe it and it may heal itself within one year. If your child cries a lot and the mass in the groin and scrotum becomes hard and cannot be retracted, you should go to the local hospital immediately.
