question: I've had upper left abdominal pain that radiates to the back. Also tenderness in left flank that also spread to the front and back. Pain is always there, but gets worse in waves. I had an ultrasound for my spleen but it came back ok. I'm on an antibiotic now, but the pain isn't going away. I also have a really bad headache, mostly in the front of my head that also gets worse as the pain gets worse. I also have nausea, vomited yesterday. Blood in urine a few days ago but that seems to have subsided. I woke up this morning and have the above symptoms as well as shoulder and neck soreness. I don't know what's wrong.
