thanks, not looking to take it for preventing any possible dcs but it is definitely very interesting that the diver you met had this belief. Was he a rec guy or commercial diver?As far as I know there is no risk about diving with ibuprofen, aspirin, naproxen, diclofenac and paracetamol. These painkillers are used quite a lot.
It seems that if you want to use a painkiller to prevent dcs, you can take aspirin. But also that is not completely known, and some people state it is a bloodthinner, that increases risk of bleeding. I met a diver in 2012 who took for every day decompressiondiving 2 aspirins to prevent dcs, he absolutly believed in this. I never tried.
