I feel etching while urine at the hole in and around. For this I contacted a Doctor recently on July 2, 2020 and advised me to have tab. Niftas 100 after meal twice, Azithral 500 before meal once and locally applied Dermosav plus. I have taken all. But before two three days it is again started. So, what should I do? I had examined urine R E and kidney function test on may 5, 2020 but almost normal.
