Butterfly Milkweed leaf, are these galls?

Butterfly Milkweed leaf, are these galls?
100 Acre Wood, Winneshiek County, Iowa, USA
October 22, 2016
In searching for evidence of Gall Flies, I collected more leaves of Butterfly Milkweed, Asclepias tuberosa
Are any of these 3 leaf disturbances internally insect related? If not, I'll frass.
This is #3, thickened ridges, upper side of leaf.
