I'm having this persistent pain along the right side of my sternum and it's starting to worry me. I've had several tests donea breast ultrasound, MRI, X-ray, and even an echoand they all came back normal. I'm wondering, could costochondritis be the cause, and if so, is there any imaging that can detect it? I really need to figure out what's going on.
