If you haven't gotten started on that swelling/redness by now, run, don't walk to the nearest Dollar Tree or such and get a 2 lb. carton of Epsom salts (magnesium sulfate) and start doing hot epsom salts compresses 4 times a day to take care of it.
Mix it about 1/4 cup per quart of water as hot as you can stand to wring the cloth out without burning your hands.
