C5-C6 cervical disc herniation & chest pain

Hi, i have a big disc extrusion in the neck C5-c6 (did MR) which was diagnosed 3 months ago. I had tingling jn fingers, neck pain & constant chest pain (which is the biggest issue). My biggest worry is chest pain. Went to the ER & also privately went to see a cardiologist (we did blood work, ultrasound, ECG, ECG on a bike) & according to him my heart is ok. Only logical idea is that chest pain is somehow connected with my neck herniation, but when intalk to my nevrologist he says there is no chance that chest pain comes from
neck. Any advice, experience? I really dont know what to do.
