One month old kitten with blister like sores, sores heal and then fill up again. New ones keep appearing, any ideas?

There are a lot of things it could be, you will more than likely need and antibiotic for the kitten, the safest bet it a trip to the veterinarian, you could research the symptoms on Pet Education.com but it would be safest to go to the vet, most of us her are not vet, and would more than likely give you a wrong answer and worsen the situation.
