The answer is yes, even a tiny stone, the size of a grain of sand, can cause tremendous pain.
When the stone does not move, you will not experience any pain or renal colic or get any infections. Once is starts to move, you will experience the pain, sometimes you will have blood or sediment in the urine. A urine test sometimes would show leucocytes, blood and or protein. Sometimes there is nothing picked up on the urine test.
What you must do is to drink plenty of water - about 2-3 litres per day so as to flush it out.
As you are male, when the stone, or grain of sand passes through your urethra you may experience severe pain as it is passing out. This is because as it travels down the thin tubes it is scratching.
If you feel in extreme pain, catch your wee into a container to see if anything comes out.
Once you have had a stone, the chances of you getting another one are much higher.
If you are lucky enough for the stone to pass on its own, if you catch this, get it analysed to find out what caused it.
Don't forget to keep drinking the water.
When you have your appointment with the urologyst, he will be able to monitor you to make sure that the stone is not stuck.
