ESA Tribunal and work

Hi
I am waiting for my tribunal hearing which should be in the next few weeks or months as in my area it is a min of 52 weeks wait. I am a nurse and want to keep my registration. For this reason, I undertook some training (unpaid). I also di 1.5 nursing shifts, following which I couldn't get out of bed for the rest of the week...... These were a total of 18hrsnot been paid for them and not sure if I will get paid but that isn't important.  Do I notify ESA regarding these? I had intended to try to go back to work again but now know that it is impossible. I was in support group, then assessed again and put into wrag god alone knows why but mandatory appeal uphel the decision so I am off to Tribunal. Any advice would be greatly appreciated.

Cheers
Andy
