well i went from being normal to now totaly in pain from everything.
And i'm in my early 30s. I hate it but.........that's how life is.
Regarding your colds, allergies...abdomen pain. , I'll give you an example of something i had a few months ago. I had always been a person that when got sick.. just went through it and got better.
But that time, it started as SORE THROAT.. extreme. then to flu + sore throat.. then for some magical reason it went to ear pain extreme and my ear drum rupture veeery badly. it was soo painful.and like that the cycle went..then my ankle started having problems.. and i said "that's it" i hope this will be the last thing. Then POW now i have chest pain and i feel like i'm broken. can't even sleep.
Perhaps our normalness as we grow is a modified version of what normal is now. Sure you will go towards some normality , be patient and positive. Like me, i don't know what's gonna happen but if i can live even with limitations.. that's my normality. that's me. there's no other way. we just live with what we have.
have patience that you will be better. don't give up.
I just kinda hope thie DRs were free

or at least someone to give us hope and advice.
