Usually when a man says he's in pain, Dr's will take them seriously. They figure you won't complain if you aren't in extreme pain. That being said there are still a lot of Doctors that believe Fibro is a condition of Women. I know different. It runs in my family and I've seen the signs in my son. He fights it and will not complain most the time, but it shows in his body and voice tone. His Father was diagnosed with it around the same time I did. He seems to have recovered. So we know it is possible in young people. Here are some reference points:

We have enough stress in our lives even without someone questioning us and our pain.
I have learned over the years to ignore those people because the only people that matter in my life are my loved ones.
And my loved ones do not question me, they support me.
In the past if someone did question me I would respond with four simple words; "If you only knew!" Then I would walk away and leave them standing there.

Nobody is too young for this. Although a friend if mine sister had it young and was bedridden and one day came out of it. God blessed her hugely.

I'm 23 and I've had it since i was about 13 so age doesnt matter. And anyone can get it, i think it comes down to genetic predisposition and also to traumatic life experience (physical or emotional). Don't let people get to you. Even when you're a woman at the age that is typical for people to have it, some people won't believe you. Its hard in a society that doesn't acknowledge an issue when its not visible. When someone asks if its in my head, I like to say.. yeah its in my head the same way the pain would be in your head if i punched you in the arm really hard right now. (Wanna see?) - last part depends on how peeved I am or if im joking or not lol. Keep your chin up and F the haters.

There are a few men on this site that have it. I have also meet a few men that also have it . It is more common in women but men do get it too. I don't think age has anything to do with it in the beginning its if you had a trauma in your life that has set it off. Hope you have a good day!
