I already suffered pelvic/kidney pains caused by a stone. Why does my urine burn/bleed? how much longer?

The severe kidney pain started on Monday and lasted about a day and a half. Then I began to feel severe bloating, cramping, and pain in my pelvic area. That lasted about 3 days. All of that pain is gone now but I realized it wasn't just a normal thing so i did research and realized I probably had a kidney stone. Now this morning I woke up and felt great. Then when I read some more about kidney stones i drank about 10 bottles of water in rapid succession. Now my urine has been began to burn and blood is coming out, I think this has to do with the fact that i can't stop urinating. I was just curious as to what stage I am probably in into the process and how much longer it will last.
