Would you consider subjective data, such as a patient stated "I am in pain," to be a fact or an opinion?
This is a debate I am having with someone and just want to get the input of others. I believe it to be fact because something such as pain cannot be proven by any other means other than someone stating that they are in pain, which, to me, is a fact. It is not something that can be disproved, the person in pain is the only authority over the pain.
What's your take?
