Anyone have an idea of what this could possibly be?

For the past couple years I've been getting this pain in my lower right abdomen like right next to my hip bone almost, its usually just q stabbing pain here and there but here tonight its been every time I take a step. I've felt it in the left side in the same area a couple time too. Also if my bladder its full it hurts really bad. The other night I woke up in the middle if the night because had to pee and was so in pain it hurt to move. What organs are in That area? What could this pain be? I know a doctor would have the answer but I cannot afford to go
