From 7th early morning suddenly i got a pain at lower back . Got a usg done and report came that i am passing a kidney stone 4mm and its in the vuj. Whole night i was in pain ( not unbearable but uncomfortable ) . Drank a lot of water and used hot water bag for pain relief. 8th morning pain vanished. But at 2.00 am i am again getting faint pain lower back. I avoided pain killers on 7th as pain was not that much. Pain now is tingling and radiating from lower back to groin (bearable ) lest than that of 7th. I have a work trip on friday. Please suggest any medicine which could help in passing the stone. I was suggested to have Citralka .
