Thick milky urine now is pink and has chunks of flesh in it.

I have a UTI....I think. I have had a couple before, so I know what they feel like, but this is just slightly different. There is the burning, the tiredness, the milkiness, and the bit of blood. There is the pain in my bladder and all that. But this time the pain seems higher. Like it starts out low, and then moves up higher into my abdomen. And today when I used the bathroom, I noticed chunks of flesh are coming out too. What could this be? And what are my natural options? I will go to a doctor if absolutely necessary, but I much prefer natural routes. Please help. The pain today is ten times worse, and I am getting slightly worried.
