I am suffering from urine burning for last two months when there was a mild urine infection which with antibiotics got cured within two days but the burning is still persisting and is all the time there and not confined during the time of urine passing. I am 69 years old with benign prostate of grade 2 with no problem of flow or frequent urination with normal post void residue. Tried flavospas, zocon150,emanzen D, zanocin and tamdura with no relief. What can be cause and medication for it. Burning is external organ all the time.
