About 11 years ago I had my back and shoulders done. HURT!!!!!!!!!!!!!!!!!!!!!!
The laser hair removal was the most PAINFUL experience I have ever gone through in my life. I was told it would feel like a stinging from a rubber band. Well, after my experience, that was one big-ass rubber band.
I had multiple treatments. By the second, I took three handkerchiefs to bite on during the procedure. By the end of the procedure, those handkerchiefs was completely soaked and dripping with saliva.
Some areas hurt more than others. For example, nearer my sides and up near the armpit was just excruciating. Conversely, the traps area didn't hurt as much.
In the areas where it didn't hurt so much, most of that hair has grown back. In the areas where it hurt the most, it mostly has not grown back.
I think maybe they have better machines now. I wish you luck
