Hello,
Welcome to Healthcaremagic.
I think you may have either kidney or bladder infection.
Sometimes kidney or ureter stones also cause burning micturition with
back pain.
As females have short urethra, they are more for
urinary tract infection.
Please note the urine whether it is normal or blood containing or white coloured or dark coloured urine.
Is there any rashes in genital area.
You already had kidney stone before 3 years.
So you may have recurrence of kidney stones now.
Please do an
ultrasound abdomen and pelvis.
If it show stones, treatment varies depends on size of stones.
Also do
Urinalysis and culture to rule out infections.
In addition you need pelvic and abdominal examination to rule out any gynaecological cause.
Then
consult a urologist.
Drink plenty of water .
Hope this helps.
Take care.
If any doubt, Please reply.
Regards,
Dr.Manjeth.
