You can turn the dial one click at a time. My doctor told me to start with half dose, which is 4 clicks (the point between the two arrows). I started mine two days ago. I definitely feel the needle and do not like it. I’ll continue to do it because I have osteoporosis in my right hip and osteopenia in my left hip and spine. I avoided it for a few years, but I saw a classmate with severe osteoporosis a while back and decided it was time. Hope you are doing well with yours.
