If you're going to do the soak - make it really warm water and if you have epsom salts - add a bunch! It will help draw out any infection - like if an infection has set in into the top of the toe nail.
Ha! You got everything but the side of the toe I wanted! I knew I needed to be more descriptive! The toe with the swelling... I can see one side. In the very last picture above, the part of the swollen toe that is facing your hand....does it have a scab?
