There is also the possibility that your little girl has a urinary tract infection but usually there is fever.
Your little girl should be examined by her physician to determine the cause of the painful urination.
Some additional reasons I may think of:
- A lower urinary tract infection (called cystitis - usually there isn't a fever in that case).
- If your daughter is recently being toilet-trained, is retaining urine or if she is constipated she may also be having bladder spasms that can be described as "burn to vagina", So avoiding constipation and teaching your child to have regular voiding will definitely help.
- Also we need to rule out what we call a "vaginal voiding" where a part of the urine coming from the urethra during voiding also pools back into the vagina and causes its irritation. Its treatment requires teaching your child a proper voiding technique that the physician can explain to you.
