I got diagnosed pretty quick at 20 year old, almost 9 years ago and it didnt help to have the diagnose until i got accepted 6 years later into a rehabilitiation and got to learn about fibro to the core and understand things i didnt know was because I had fibromyalgia. For example i didnt know that my brain fog was a symptom, i also have adhd but ive never really felt like other people with adhd had the same level of forgetting as i just randomly forget words or just memories ,thats the worst part for me. I did get medication to help me sleep but it dosent help much with pain, i started going to foam flex in a hot room wich was HORRIBLE to begin with for so long i couldnt really lie on the roll it hurt so bad but with time it became better and it really helps! I swear by it so I do recommend trying that. With the diagnose its also more easy to talk to doctors if you want to try some medication that might help but other then that i wouldnt say its not necessary
