Almost feels like Kidney pain

Kristel
Maybe someone else has experience this:
When I use the bathroom or am laying down or twisting to loop my belt it feels like my kidney is bruised and sore, other times it's a sharp pain and it lingers long after it would have normally gone away. 
I feel it most when using the restroom and it makes me worried. 
Anyone else have this pain?
Oh. And it's my right side.
