I can be such an idiot sometimes...
For some reason, I got my back block injection date mixed up....thought this whole time it was meant for the 12th of September, but it was really set for the 5th.
Looked at my surgery guidelines...says 9-5-12 right there.....right next to 8-12-13 as the date when I signed. /facepalm
What is wrong with me...
