My husband had a massive boil which started as a little pimple. Within a day, he could not sit or sleep comfortably. Pain relief did not work, so we began to speak to the boil, declaring this was a plague of Egypt and we have been exempted from this plague therefore we command it to go. Instead of drying out, it rather grew larger. We took our stand, declaring, as Jesus spoke to the root of the fig tree and commanded it to wither and it obeyed. So we began to speak to the root of the boil at every opportunity. Within a few days it opened up massively and started drying out.
