Thanks for writing your query.
I would like to know few things like :-
1. Are you having fever
2. Are you diabetic?
3. Are you taking some medicines?
4. What is your age?
Presence of blood, protein and white blood cells along with back pain
indicate that there is infection in the urinary tract
You should drink plenty of pure water.
Also get your Kidney
Function Test done.
I hope this is useful to you. If you have furthur doubts, I will be happy to help.
