I am not sure what exactly the OP is referring to, as no link. This thread seems to have been raised with the sole intention of baiting TTT. I'm sure if TTT did that he would be suspended, but there we go.
However ther seems to be two news items here, one dates back to mid lasat year and the other is related to this in the DM:
https://www.dailymail.co.uk/news/article-9442963/New-warning-powerful-painkillers-GPs-told-not-prescribe-pills-chronic-aches.html
which hgas the headline:
"New warning over powerful painkillers: GPs are told not to prescribe pills for chronic aches with no known cause... and recommend exercise instead, latest guidelines say"
So, you can have pain killers if its diagnosed. The OP is incorrect.
Of course, for some, getting diagnosed these days may put paid to getting them (unless you have covid of course)
