Chiropractor vs Massage

Hi mommas

I've been having terrible neck and back pain on and off from holding the baby, nursing etc. I'd been thinking of getting a massage done but then i saw some mommies talking about chiropractors here.

Wanted to know if it's worth going to a chiropractor instead? They seem to be really expensive here in the UK, (charging an average of $75-100 per session). Need some more info about chiropractors too- why are there multiple sessions with them? Is it important to have multiple sessions?

How long/how many sessions does it take to heal the back etc. sorry if the questions seem stupid. i have no idea about how they work...

Is it worth going to one or should I just get a nice massage?
