Have a couple of popped blisters on my feet from new high heels. Put neosporin on them, but they hurt a lot! Anything I can do to expedite healing?

Throw away the neosp. Neosporin does not prevent infection. It may interfere with healing. It is a common cause for allergic reactions. Avoid friction. Use water to clean and soothe the areas. Lubricate with vaseline or Aquaphor.
