Sorry to read that, I had my fair share of health issues too and I can't say that I enjoy these hospital visits. This one was not that bad though.
There are quite a few restaurants or tapas bars near the hospital but I never tried the cafetaria inside the hospital, I should, because the hospital food there (when I was submitted one night last year) wasn't bad at all.
Wishing you the best when you have to go to the hospital, hopefully there's some positive news!
