Hello
Over the last week, I've noticed red marks on the top of both my big toes between the nail and the main part of the foot.
There are small red dots as well. I thought at first that this could be a reaction to using a substance for clearing a blockage in my bath and then standing in the bath to have a shower the following morning, but I would have thought that any reaction would be on the soles of my feet.
The marks aren't painful, but they are itchy.
The skin is also harder in this area, particularly on my left foot where the marks are more pronounced.
I've attached a photo of the marks on my left toe if that helps.
Do you know what this could be?
Thanks
