You should go to the store and get hydrocortisone cream and apply that for a few days and that should help those bumps go away! I read that from a few people on other threads and also from a few YouTube videos where that's what people's dermatologist told them to do

I am experiencing this same thing happening to my lips. I am on week 3 at 30 mg a day. The blisters are spreading and vaseline helps a little but not too much. Did yours end up going away after some time?
