Severe Headache With Pain In Shoulder And Severe Cough

My friend has been experiencing really bad headaches with pain which is located on her right side. The pain covers her head, check and in the top few vertebrae along with her shoulder . She has had an MRI scan which was clear of any shadows etc and she has been diagnosed with NT (sorry I can’t remember the correct name but this is how its referred in the medical profession), however she also has a very bad cough with loss of breath??? She has seen a chiropractor who has informed her that it is nerve related and that there is compression in the first few vertebrae and she is about to start treatment, but she has been in pain now for nearly a month with the pain ranging from a 10 out of 10 early in the morning to a 3 out of 10 in the evening, all of which is being managed by some strong pain killers prescribed by the doctor. I am worried that there have been little signs of improvement and that it is effecting her mental state as well, she is NEVER unwell Is it possible this could be pneumonia?
