“also I read the suggestion about covering the needle with nail polish and sanding the tip so you don’t burn the surrounding skin. has anyone tried this? is it a good idea?”
I think no one answered that part of her message and I am curious about the very same thing .
Anyone knows the answer?
By the way, what does “sand” mean in this context?
Does it mean that you have to put nail polish all along the probe BUT in the tip? or something else?
