nofap and spine issues .....

Hii guys, from about 3 years I am facing spine issues. I am only 16 but having pigeon chest ( pectus cerinatum ),with hunchback (kyphosis). Sometimes I feel pain in lower back. I consult doctor but he always give some painkillers. I try self to fix it by performing abs and back exercises and stretching. But they didn't show positive results anymore. I don't know if it's genitical or by my mistake but I wanna fix it. Does anyone face similar problems? Does nofap effects on poisture related problems? What should I do to fix it? Have anyone fixed it through exercise or medications? Pls reply honest because sometimes my body structure make me feel awkward and negatively effect my confidence level.
