Puffy eyes!

For the past four days I have woken throughout the night feeling quite ill - sickly, shakey, needing to pee.  And my eyes are puffy when I wake and the puffiness remains throughout the day - so my eyelids look like they are sagging over my eyes constantly!  I have lost my appetite too and seem to feel full after only eating a small amount.  I am only really eating because I feel I should - and not because I am hungry.  I am starting to worry as I look and feel terrible.  I have stage 3b ckd.  Anyone shine a light on why I could be feeling ths terrible all of a sudden.  I was taking nurofen until a fortnight ago but haven't touched any since.  I just take 2 paracetamol in the morning first thing because I wake up feeling so tired and terrible but that is all.

I have been taking a couple of Aquaban in the evening to try and get rid of the puffiness from my eyes but it couldn't be helping?

Oh and I do seem to be peeing more and no swelling in my ankles - just my eyes?
