I agree with all PP's hun, at day 4 panadol is definitely not enough. I was still on some kind of strong drugs that they gave me while in hospital until day 5 then I went onto the equivalent of panadeine forte (but without codeine which I can't have but the same stress) as well as Voltaren as well. I would be speaking up because as you said it is major surgery and 4 days is no time at all to heal. xoxoxo
