Yes, so recently I noticed a buildup of a foul smelling material on my left big toe. I inspected further and found that there is no fungus, according to the symptoms of toenail fungus, and I don't have an ingrown toenail hence the fact that some pain is located where the nail leaves the body. The pus-like substance, slowly coming out over time or all immediately if I force it out, crystallizes over time and is foul smelling. There is only pain when I put a lot of pressure on the area.
