Had em and got the good drugs.
If you’re going to the docs in the morning are you sure it’s kidney stones? Most people end up in an ambulance I’m told though I’m reet hard and my missus drove me into to the on call docs (screaming and crying in the back of the car :-))
Drac, IM diclofenac can and does cause tissue necrosis, and its use when alternatives are available is pretty much indefensible these days.
I know a chap who was pretty much crippled by the after effects, with muscle abscesses that required months of surgery.
Up the bum is best.
Does that include the little oral tablets? Didn’t know they were so nasty, I was told they were just ‘super ibuprofen’ 😀
