I cannot download the images, the address does not work. I also must remind you that I generally need to see the complete series of images to understand the disorder. You can read up on Scheuermann’s kyphosis on this website. There is an entire topic I have written.
Bulged discs are part of the disorder. Sometimes these disc bulges can be pain generators by themselves but generally the pain is generated by the abnormal angle of the curve overloading the actual disc surfaces. See IDR in the lumbar spine to read something relatively close to this disorder.
The longer you stand, the greater the intensity of pain will be. When you lie down, the pain should diminish. You can try to work on extension exercises (rowing and such) to reduce the pain of prolonged standing.
