Do you have scoliosis if:

-you have the wing bone in the shoulders equal (I don't really know cuz I think one of my shoulder muscles is more prominent than the other, i guess)

-You have equal hip height

-equal shoulder blade level

-One nipple slightly lower than the other (i am not sure in this one cuz one of mine has a oval shape and the other a circular shape so I don't know if one is really higher than the other)

-If you touch your backbone from top to bottom and you feel only one smooth curve (if you go all the way down, you can feel every vertebra although some are not completely aligned)
