Kidney stones are small. They can be as tiny as a grain of salt or as big as a corn kernel. You may not feel anything and never realize you even had one.
But other times, you’ll know about it. That’s because flushing one out of your body as you pee can hurt, sometimes enormously.
That pain you feel as you pass a stone is the main sign that you might be taking in too much minerals and not enough fluids. That imbalance is one reason these pebble-like objects might form. The stones can be brown or yellow, and smooth or rough.
What Does a Kidney Stone Feel Like?
When you have a kidney stone, you may not have any symptoms -- that is, until the stone starts to stir.
Symptoms can vary and can be mild or severe. The most common one is pain. You may feel it:
- In your side or back, below the ribs -- and the pain can be very intense
- In your groin and lower abdomen
- Come and go and get better or worse
- As you pee -- and you might have to go more often than usual
The pain can shift around in your body, from your belly or back down to your groin. This means the stone is making its way from your kidney through the ureter and closer to your bladder.
When this happens, you are more likely to feel a burning when you pee or have more urges to go.
Sometimes, you can spot the stones after they exit.
Do Bigger Stones Hurt More?
Surprisingly, the size of your kidney stone doesn’t match the degree of pain.
Sometimes smaller stones can hurt the worst, while big stones might just give you a dull ache.
