Do you have any history of renal stones in your family?
Stones are usually known to move after one has been resting or lying down for some time.
If the stone is smaller than 5 mm, it will pass through the tract.
Larger stones will need other intervention for their management.
You can do the following to prevent and reduce the occurrence of kidney stones:
Drink at least 2 liters of water per day.
Increase intake of citrus juices.
Take paracetamol for the pain every 4-6 hours, but do not continue it, without seeing a doctor, for more than 3 days.
Avoid foods rich in oxalates such as beans, meat, etc.
Do not resist the urge to pass urine.
Try to pass urine as frequently as possible.
Do keep us posted on your doubts and progress.
