should i get a stick? (shoulder problems)

First, hello all
im kinda new in to the forum, and also into fighting games...
im currently using a ps3 controller for my sf4, but im willing to spend the $ into a good stick..
but then i have this question.. will i have any problem with my shoulder?, since i have problems in the left shoulder (stick)
srry to be so vague, but what do u guys thinks? using the stick make your shoulder move alot or smthg?

hope i can get some insight, since i dont want to spend $$ in something that i woulnd be able to use after :/

bye !
