I remember when you were booking your trip to Greece. It was amazing that you were up to it. If I remember right, you enjoyed yourself and got much needed rest and relaxation.
The thing that has me most concerned is how you are feeling ill.
Have you lowered the dose of some of your meds? When my patches wear down, I get flu-like aches and feel sick.
I've been gone for a bit, so am not sure how it went when you had your stitches checked or what the Dr said.
Does your back still look the same as in the photo you shared?
Your battery site is still very vulnerable, so if you slept on it wrong or irritated it somehow, it's probably gonna hurt for the next day or so.
I'm so sorry you are having these symptoms this late after the operation.

Do you have a follow-up visit with Dr scheduled?
edit to add: I shoud have read your other thread first. you've explained some of this over there.
