Should I be worried, yes, no? overthinking?

Anonymous
So a little back story, my boyfriend of almost a year has a girl best friend who he dated for 3 years previously, they’ve been broken up for a couple years now and he states they’re only friends which i believe because nothing has happened to make me think otherwise. But what I’m wondering is if I should be worried about this or not, so my boyfriends back hurts a lot of the time from work and so basically I guess he told his girl best friend about his back pain and I guess her friend offered to give him a back massage (she does that for work) for much cheeper then it usually costs where they work, and i know i probably shouldn’t worry but I’ve never met the girl best friend and I have no idea who this friend is and as far as I know he’s never met this “friend” either so it seems weird to me that she’s offering to give him a service for way more then half the normal cost of it. I don't know if I’m just overthinking or being insecure, I need advice/opinions. Thanks
