Hello everyone! I have this nail in this situation for a few years now. At the beggining of the year I went to a dermatologist and he requested some tests for fungus which result was negative. Also he said that the lines pattern are not like fungus, he anyway sent me meds to try as it was fungus for 1 month, but I got no an improvement. If you check the 1st picture you will see that it’s sunken in the middle. I never had any impact in that toe. What else could it be? I feel ashamed every time I go to the pool because of it
