you say that pain in itself is not a reason to present to A&E
No, I said it's not an emergency. I also said anyone was welcome to go to A&E, OP and your good self included.
I disagree with you, and you are still trying to argue with me
Are you not accustomed to people disagreeing with you once you have spoken? That's how a discussion goes, usually.
I have presented to A&E with chronic pain that I am unable to get under control, and many other people have.
Good job, sincerely hope it helped. What would you like me to do with that information about your choices?
GP’s won’t prescribe morphine IV so the only option is to go to A&E (GP’s own words).
All jolly good, and true. This is a valid route to treatment, as dictated by the system. You should go. Still not an emergency.
at least I don’t say they shouldn’t be at A&E as their pain isn’t worthy of treatment
I should hope not, that's unprofessional and not your place to say. I haven't said this either, in fact quite the opposite. Please, absolutely do go to A&E if you feel it's necessary - pain is still a valid reason to go to A&E, it's just not an emergency in and of itself. OP is the one judging you for why you're there, not me.
