Hi Billyy and welcome!
I have not had your particular surgery...but have had other procedures done, and I found deep breathing to be a great help.
It will help you avoid feelings of being faint, as well as distract you from the local anesthetic shot...since you will be counting and focusing on your breath.
Inhale through your nose for 4 counts...hold for 3, then exhale slowly for 4 more counts.
Best wishes, and know that we will be cheering you on! Check back and let us know how it goes if you wish...
...and post anytime here for anxiety support!
