Hi jenny,
the first thing I will say is really check them out {as with any service person these days} to be sure they are well trained or have real knowledge and experience - don't go to any beginners.
Many times you can go for an evaluation {free or discounted} before committing to the one of your choice. ask about it.
Gentleness is a good thing- mine spec in geriatric care so he is.

I have some links on TRPs that can explain better than I can-
Triggerpoints and referred pain and stretching:

a very basic explanation of a Triggerpoint- a muscle can get so tight from overwork or static tension that a small knot {TrP} of tension will develop in it.

after I read more about chiropractic I wasn't as nervous about it-
and I feel I can trust the DC I chose-
Chiropractic care info- a good one can help with many symptoms:
