### input:
Two nights ago I woke up due to a very strong pain in my right side below my belly button and to the right of the pubic area.  During the course of the day this pain shifted to low down on my back on same side.  By the evening the pain had returned to the front but was severe enough for me to call 111 and ask their opinion.  Two options suggested, first to go in to see the out of hours doctor then or wait and see if got worse.  I chose the latter but by 4 a.m.  the pain was very bad.  I again rang 111 and was told to go to the local out of hours service tosee a Doctor. This I did and the GP examined me and said that I had blood in my urine so her diagnosis was renal colic and renal stones.  She also mentioned possible infection.  She rang Casualty and I was sent there.  During the morning I was given strong painkiller rectally which greatly helped.  CT scan of my kidneys was normal as was two subsequent urine tests.  The consultant told me that I had probably had a stone which I passed.  Yesterday evening at home the pain in my back had gone but I still had a niggly discomfort in my flank.  This morning the pain in my flank has returned and Iam unsure where to go from here.  I did a urine sample which on looking at it is slightly dark but I cannot see any blood in it.  I would be grateful for your advice as towhat I should do from here if anything.

### output:

Hello! Thank you for the query. Your symptoms indicate kidney stones indeed. Lower right area is where ureter is located. So a stone in the ureter which has stuck there will give symptoms like yours. Please note that the stone which you have probably passed does not have to be the only one. Small stones can also be passing right now, so you have less intense pain. Dark urine can be caused by low liquids' intake. If there is no intense bleeding in the urinary tract, you won't be able to see any blood in your urine. Urinalysis can do that. I suggest you to follow this steps:- increase mineral water intake (even 3 liters/24 hours)- start cranberries supplementation- increase physical activity (like running or jumping) so the stones can get out - in case of pain, hot bath or Buscolisine can be helpful this won't help, you should consult your doctor again, have urinalysis, blood work, abdominal ultrasound and consult urologist. Hope this will help. Regards.
