5'8 and you think you are too tall? Where are you living that you think so?
Imho it's really not healthy to think that 5'8 is "too tall", I really expected someone way above 6 foot(we had already someone like that).
Is the reason it is uncommon health issues from surgery?
Yes and the fact that people wish to be taller not shorter. I recommend to contact Dr. Paley or Dr. Birkholtz for more information.
