I Have Been Having Discomfort Under My Ribs For About

I have been having discomfort under my ribs for about 6 days now. I thought it was just my right side, but my left side is slightly sore as well. Also the discomfort is around to my back kinda of like a wide belt. It does feel better when I lay down and the discomfort is not constant,however, I do get the odd sharp bit and then it goes away. My bowel movements have changed slightly, I have them, but they are not as good, if you know what I mean...some little spirally logs come along with a big one. If I press underneath my rib to check to see if the discomfort is going away it can be sharp. I do not know if I put a rib out or ???
Please advise on what I should do...go to hospital or wait it out. Also, I did have my first kidney infection in August and I did go to a walk in clinic this past Monday. The doctor did a urine sample and found no infection. He gave me a prescription as the symptoms I had for the previous infection did not fit the norm...he is sending the specimen for a culture to see if anything shows up
