My urine is clear in color but this morning smelled like gasoline and i feel like i've been kicked in the back lower ribs by a horse..also i sweat and it is gross smelling below?

That's a very...: ...colorful description but, even if I could tell you what's causing it, I couldn't treat you. Foul smelling urine or vagina discharge, pain in the low back and sweating are red flags for something that needs medical attention. Kidney stones, bladder or kidney infections and bacterial vaginitis are possible conditions that need to be ruled out or treated. Best wishes.
