I have acute needle-phobia. I booked my COVID jab yesterday. It'll be in late September. I have to think about that for the next month. I broke out into a cold sweat booking it. I don't know how I'll go with the actual jab.
Ask them to do the scratch thing. They scratch a few times at the site of the injection and one of those will be the jab. Also, look away. I used to be needle phobic, but sadly over the past few years I've needed lots of them for various reasons. Also, kids make you brave.
There is one nurse at my local GP, she is legendary, I barely feel the ones she does. I always ask for her.
