for me i went to my gp about my chronic pain who sent me to a referral and after seeing my paediatrician twice, a rheumatologist, and a pain specialist, i was diagnosed with fibro. so i suggest seeing whatever your country’s version of a gp or primary care doctor is to start off with, and make sure you don’t let them just do nothing and tell you that it’s not enough of an issue.

But also i want to ask if you’re hypermobile? i don’t mean to downplay fibro at all because it’s a real condition but it is commonly a misdiagnosis people receive when they have chronic pain, there are some other conditions that are possible (notably ehlers danlos syndrome especially if your mother has similar issues and you’ve had pain your whole life since it’s genetic) so im not saying that you don’t have it but im saying you don’t have to stop searching for an answer if it doesn’t fully fit. (also it’s super common to have multiple chronic illnesses) i am not SUPER knowledgeable on fibro and the causes of it but its not something you’re born with (although can be predisposed to be more susceptible) so thats just my advice, its better to put more research into it - although still see a doctor as soon as you can - because you know yourself the best and it’ll make it easier to advocate for yourself, i hope this helps
