Should I go to the doctor for this pain?

For roughly five weeks I've had what was diagnosed as bronchitis, but what I'm starting to suspect is probably whooping cough. For the past two days, my cough has been so intense that it's caused a constant, sharp pain on my shoulder, around the same area my friend felt pain when she had a cough so severe that it cracked her rib. It hasn't been around long, but the pain is moderate to severe depending on what I do, and constant. It hurts to lay down, sit down, walk, etc. I'm not sure if it's serious enough to warrant getting an x-ray, but I'm getting worried about the severity of the pain. What should I do?

Obviously you must go to a doctor. The earlier you go the simpler and cheaper will be the cure. Delaying may complicate matters and make the treatment more painful and expensive.

You need to go to the doctor as soon as you can. Few months ago I had a terrible back pain. I couldn't move. It hurted me all the time. Thanks a lot *mod edit* , after rehabilitation and physiotherapy I began to come alive again.
