Hello ronroush7
This is a worrying time for you and it will get better after you talk to the surgeon tomorrow.
Where is the operative site?
Does it relate to IBD, inflammatory bowel disease or is it for something else?
You mention about surgery to your head----did you want to talk more about it?
Sorry you have these anxious moments, as do we all when it comes to any surgery.
Feel better soon
Hugs and best wishes
