Hi
I will try my best to answer your query.
Burning micturation and
back pain may be due to
UTI or due to stones in
urinary tract. urethral stone can cause burning micturation. cause should be found and treated.
For UTI
antibiotics should be taken and if stone is detected it should be removed.
Before taking antibiotic urine routine and culture should be done.
I advice you to see physician.
Hope my answer will be helpful for you.
Take care.
