Hello and happy pride month! I don't know if this is the right place to ask this so my apologies if I should have posted this somewhere else. Also, sorry if people have already asked this a ton, I couldn't find anything about this.
My names Oliver, I'm FtM (he/him and they/them pronouns), I'm currently 13-years-old (turning 14 next month), and lately I've been having some breathing difficulties. I've been chest binding for about a year now and started having breathing difficulties about 4-5 months ago. I've noticed I can't take deep breaths anymore and it's become especially hard to breathe after exercising (and not because I'm out of shape or anything like that). I don't wear my binder when I'm exercising, I only wear it for a maximum of 7-8 hours (i haven't worn my binder since summer started), I don't wear it when I'm sleeping, and I follow all the binding rules that I know. My binder fits me well and it's not super tight so I don't think it's too small but I think my breathing difficulties are caused by me binding.
I'm really worried that I'm damaging my ribs and/or lungs and that my breathing will get worse. Does anyone have any suggestions on what I should do to fix my breathing problems?
