A 1 ltr shampoo bottle fall on my toe finger it becomes black but its not paining that much should I worry

A. Mam 1 L is quite a lot to be falling on the feet of the child must be like a full bottle so the child may have got hurt and also saying the place has turned black so I would suggest you to check with your doctor once regarding that and also check if there’s a pain you can give paracetamol as painkiller to reduce pain
