I have pain in my lower left side of my

Patient: I have pain in my lower left side of my back, left hip pain, and lower left abdominal pain. I also have a small rash on the inside of my left thigh. I went to doctors earlier and he said I have a bacterial infection for the rash. He didn’t really speak about the pain in my abdomen, hip, or back. Just curious as to what that might be?

Doctor:
