When my open sore is at the point of being able to be pinched closed, I put a dab of super glue with a q-tip to the middle of the wound. ( it does not burn or sting) pinch it closed and hold it for 10 to 15 seconds. It closes it so it will heal faster. Nothing worse than an open oozing sore. It closes easier if the sore is very moist from being covered all day with neosporin and a bandaid. Sure it is a little bit crusty but much more attractive than an open sore. Don't pick the crust! Maybe do this before you go to bed to wake up to a more closed/ healed sore. Good luck and God bless. We are all in this together.
