I've been having pain on the left side of my neck and shoulder for the past couple of weeks, and sometimes I feel some chest pain too. I went to the doctor and got an ECG, but it came back normal. I'm not sure what to do next. Should I see a cardiologist or maybe an orthopedic doctor? It's really starting to worry me, and I'd appreciate some advice on the next steps.

orthopaedic opinion is required
