are you still there?
how old are you?
any other medical problems?
any issues with urination?Any trauma?
any heavy lifting
it sounds like you may have a kidney stone
or severe muscle spasm
seeing that you have such severe pain, I would suggest that you see your doctor for pain medications and a urinalysis
or you can try ibuprofen now.
and see if that helps
if it passes, then it is likely to be a muscle spasm
then you do not need to follow up with the doctor
but if it persists, then you need to follow up
or if you get fevers, vomiting or bloody urine you need to go a&E
usually these resolve on their own
if they are less than 5mm then most go away
you are welcome
did i provide you with excellent service?
