<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I ve had this pain in my in lower middle on the right side of my back since yesterday. It s really intense in the morning but yesterday it went away after a couple of hours. It gets to the point where I can t stand up straight and my eyes tear up from the pain if I so much as laugh. Today it dulled after a while but it still hurts pretty sharply sometimes as the pressure builds and releases, it doesn t really matter much which position I m sitting in it just kind of comes and goes. I figured I probably just slept on it wrong, but a couple of friends had me worried about kidney stones or some kind of infection. I don t really have any other symptoms except a few times the pain has extended to my lower abdomen for a few minutes.  <response>: HI, This pain is most probably due to renal colic. To exclude causes of renal colic you should have an Ultrasonography Kidney Ureter and Bladder, Urine RE and Rats should be done. Then after the labs treatment should be according to the cause. If all the tests are normal you just take painkillers for a regular period of 07 days that will surely relieve your symptoms. I hope I am successful in solving your query if you have furthered you can ask me. Take target well soon.
