So sorry to hear. You posted a few weeks ago, I hope you are much better now.
I only had shingles after my 4th EC last Aug, which was painful, but didn't land me in hospital. I did end up in hospital over christmas when I had a bad infection a few weeks after surgery. I also barely walked anywhere for a week then - up and down the ward, that's really it.
A little bit every day, slowly and eventually you find that you do more than you could do a week previously....
Big virtual hugs, I really hope you are well enough to continue with the rest of the chemo.
