It often happens with long term forward head use - desk work, computer, art/crafts, reading/studying.etc

I can't remember if it it called lordosis or kyphosis

Way back when I was having PT for my shoulder sx only before I knew anything about TOS - the PTs would mention kyphotic posture - but didn't go in to itin any detail -and I didn't ask many questions back then.. it was before we had internet at home.
Plus I assumed I would heal up as always and be fine....

It's more of a result of use and postures than a cause.IMO

I had a moderate "hump" by the time I went to chiropractor and after the worst of my symptoms were resolved with treatment the hump went to a more normal appearance. {misalignments and extreme tension?? perhaps}
