I recently had a small area of fungus under the left great toe which cleared (area still growing out of nail). The nail bed was normal until 10 weeks ago when I developed soreness, redness , slight edema and pain of the left great toe. That cleared after a week of using a homeopathic oil of oregano, peppermint and tea tree oil. Now I noticed about 6 weeks ago a yellow area growing out of the nail bed. My toe is numb, but I do have a bunion x 30 years. I don't know what the partial yellow discoloration nail is from.
