Gradually for me also although a lot of my ailments came to my attention when I read up on Fibro when I was diagnosed & was shocked of the pain I was enduring was related

Gradual I thought it was related to work and or being a nurse working long hours and high stress.

Gradually, I kept trying to self diagnose myself. Brushing it off as being toxic and needing to detox. Or just my Vitamin D Deficiency and increasing my Vitamin D intake. It wasn't until recently when I was having such a hard time walking and lifting my arms that I finally realized something is going on. The fatigue was debilitating. I couldn't concentrate at work. The pain all over got ridiculous. Then all of my labs came back normal. That's when I knew I had to face reality and go see my doctor.

Gradually! Went to several dr. Trying to find out why I was hurting here & there!!!

Mine was gradual to start off with, fibro was picked up because I was being tested for lupus, but just in the last 6 months my symptoms have really escalated
