😥 sucks not being able to breath normally. So sorry you’re suffering. My chest deformity isn’t bad… I actually had someone point it out to me when I was 21 and I had never noticed until my doc did x-rays and was like I’ve never seen this before that’s odd. I have a slew of other issues that I’ve always thought were more likely causing the chest pain so I have no idea what it’s really from. Personally breathing feels taxing especially if I’m tired or hurts to talk like the wind is getting partially knocked out of me. If I were to speculate I think my breathing difficulties are mostly from chronic sinusitis, hiatal hernia, GERD, vocal chord dysfunction (similar to asthma but harder time breathing in), bone spurns along thoracic spine with psoriatic arthritis and ankylosing spondylitis. No idea if this info is useful for you but I figured I’d post since I saw no one else has yet but I can relate.
