I too was nervous about having my staples removed. They had a numbing spray they put on my head and i would sure ask for that. Most were fine, but i did have a few where did let the f bomb drop. However once having them out it was so worth it.
So hang in there, ask for numbing stuff,and it will be over before you now ir.
It seems most of us are cut from center of head to the back of our ear. I was all left side, so just another phase of healing. And then you can go home and wash your hair a lot better than before to get remaining blood out.
Best of luck............you can do it.........you and i certainly have been through worse right !!!
