My 2 yr old son woke up with a blister on the outside of his nose, it scabbed over and another formed and has just kept repeating. The outside of his?

See MD. Sorry your son isn't feeling well. If the crusts /scabs are honey colored this may be impetigo. If the lesions are truly blisters which are fluid filled this may be Herpes Simplex Virus. Please get a full exam for your son a culture can be taken if there is any question to the diagnosis. .
