Hi amanda yes they usually do spread them out,usually they make you come back within so many days and then set you up for a different area if thats what you need,for instance i got one for my cervical area and then one for my thorasic which was my legs,for some reason the one for my legs really made a big difference,and i will be going back for another one but iam putting off as long as i can,iam a bigger sissy than i like to admit,but it took time for me to realize that it worked for me it was not immediate i guess thats why they say its different for everybody i really hope they work for you,youve been threw alot i hope you are feeling better.have a great day. marywoo
