Since Past1-2 week i am seeing mostly there's yellow urination, and sometimes it goes dark yellow even after drinking a lot of water as well and little bit of smell. There's no UTI or itching or anything. Just the color is coming darker sometimes. I have pain in/below/near lower left back rib idk what is it, its there since nearly 1-2 months and Its a dull ache only when i touch it or while sleeping i change sides i feel it, can these be related..
