Pain chest and breast. C5–c6 disc bulge?

One year ago, I was in an accident. Shortly after, I experienced chest and breast pain. I had an X-ray and a breast ultrasound at the time, which were both normal. I was took tablets for at least 2m. But However, the chest and breast tenderness persisted.Recently the pain worsened, and I began a new course of medication. While on this medication, I developed new back pain after 1m, then after 3 to 4m sudden arm pain and hand pain . A neurologist advised an MRI of the cervical and dorsal spine, which revealed a mild C5–C6 disc bulge. The medication has helped reduce the back pain, arm pain, and tingling sensations, but I am still experiencing chest and breast pain on both sides, which is often triggered by movement or while sleeping straight. Is this chest pain caused by the tenderness, or is it related to the C5–C6 disc bulge?"
