I suppose HAs may feel uncomfortable if you are not used to wearing them. I've been wearing HAs most of my life and can't really feel them now, even though they are quite large compared to some.
I did get an odd comment from an elderly friend the other day, who has recently started wearing HAs. He looked at mine and said 'Wow, your HAs are twice as big as mine!'. Maybe that made him feel less self-concious, I don't know?
