<s>[INST] I just returned from the emergency room and I am still in horrible pain.  I felt the need to pee and suppressed the urge for a couple of minutes.   I was hit with a pain so bad I couldn't stand up straight. The pain is on  my lower right and goes through to my back. The emergency doctor thought it might be a ruptured cyst but I think it has something to do with my bladder.

Thank you. </s>
