If they they work and they are besically, non- invasive whts the propblem thman... yes my great spelleinging is is back.... I had one round and to be honest a second dose was just not worth the cost..... for me I found the trigger points given by By Dr Togut, using Marcaine in the exact areas... hurt at first than in a bit tthan it gave the area enough timeto relax and ease up on it's own for a while.......just my comparison to BOTOX
