<s>[INST] 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. [/INST] 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 R/E and RFTs should be done. Then after the labs treatment should be according to the cause. If all the tests are normal you just take pain killers for a regular period of 07 days that will surely relieve your symptoms. I hope I am sucessful in solving your query if you have further you can ask me. Take care Get well soon. Regards, Dr. Azhar Sattar </s>
