I have had mine since 2009, and only DX with fibro since March, but I don'tsee where my fibro is worse or more frequent than others. Seems like when and why my flairs occur it is the same as others. But if I felt like this before not sure I would have bothered
but my were not for the reason you are debating them, mine were purely for cute shirts reasons.
Hope if I wasn't helpful someone else will be more helpful
