I can: a simple assimilation. gd is still a common combination in
Modern Greek, so probably was back then, but it doesn't "feel right"
in Romance languages, so people tended to mold into the patterns
familiar to them?

So [migd] became [mind] became [mend].

If -gg- is -ng-, can't -gd- have been -nd- is some dialect?

Just idle speculation: Looks rather like a change that may have been
triggered by the earlier assimilation of the "ala" of amygdala to an
unrelated "-ula", then regressive assimilation of the -y to -a, like
amagdula, then amandula.
