What’s actually the deal with chicken pox and ibuprofen?

I was under the impression that you must absolutely never give it during chicken pox. When DT1 had it a couple of weeks ago his temp went up to 40.9 - managed to get a call back from GP who said to alternate calpol and nurofen. I think he slipped up, and I pointed out that the advice is to not give it - he said that the evidence is minimal and it wouldn’t be the end of the world.

Ended up seeing a different GP a couple of days later and she said she’d given her DD nurofen throughout chicken pox as she didn’t know she wasn’t supposed to...

Now DT2 has it and has entered the 40+ temps phase. I’m wondering what’s more dangerous - very high temps or giving the nurofen?! Obviously I’m already giving the max dose of calpol but it’s not enough to stop the temps.

He’s still at the blister stage if that makes any difference.

Thank you. He doesn’t actually have any signs of something being seriously wrong (temp only 37.5, none of the blisters look infected, breathing fine etc) aside from the fact he’s so distressed and I don’t know why. He could just be having a meltdown but he doesn’t ever have them, so far at least. Could just be normal chicken pox discomfort, but no idea how you tell when they can’t communicate or understand.
