My mom stepped on something in the woods that punctured her toe through her shoe. Now she keeps getting little black spots kinda indented in a little crater. They are itchy and burn a little. No athletes foot cream has helped. They are only between the toes and on the tip of the toe where she got stabbed. We don t know what went through the shoe.
Thanks for posting your query to Chat Doctor. As I understates it may be injury by wood material and probably some material left under layer of skin , that is responsible for causing itching and pain. Persistance of material under skin may lead to infection. So you need to contact to surgeon for local examination and if required removal of material. Take care.
