second the chiro, they do NOT have MD at the end of their name, don't trust their advice, all they know how to do is to give you some very scientific tests, and schedule you to come and lie down once a week for the rest of your life, they don't even know what ergo is.
but i'd at least start with a different kind of switch, if you haven't already been using ergo cherries or light topres, you should try.
