My Drs recommended Aquaphor (brand name) ointment. It works quite well and last longer than lip balms. I first used it when I got blisters on my lips during radiation. I finished treatment 6 months ago but continue to have painful blisters on my lips. No one seems to know what this is from or what to do about it. I thought it was connected to the Thrush but I don't seem to have thrush anymore, but still have the blisters.
