SSP or Quit???

[Fred]

Hello to everyone ( those who know me and those who have yet to become acquainted ).
It's a long story but I have had PPP for some time now. Managed (eventually) to stabilise on cyclosporine to the point where I got a full time job. But now I have been kicked off them by a new Dermatologist (another long story).
My dilemma at this point is that the new treatment proposed has the potential to take weeks to kick in, if indeed it does. I haven't been to work for a week. Deterioration has been swift to the point where I can walk no further than 50 yards.
Every morning I have to call in sick and I have been told I have to get sick notes to qualify for SSP. I was under the impression that my employer doesn't pay sick pay so is SSP different? Are they legally obliged to pay me it for 28 weeks? Only £81 a week I think but better than nothing I suppose.
I was originally thinking it was best just to give notice but am not sure now where I would stand ( metaphorically not physically ).
Sorry for the convoluted post and if I have posted in the wrong section.

No it's in the right place.

But personally I can't help as you know I live in France and I've lost touch with the system over there, I'll have a word with Jim he's good at sniffing things out about the UK.
