I started gauging 4 months ago , and I am going very slow . My ear lobe is stretched and it currently has 5 mm , recently i tried to stretch it but it did hurt , not like usual so i remained at my size , without continuing the stretch. Now , i feel a little discomfort in my ear lobe and it seemed to turn gray . Is it necrosis or maybe Some metal paint from the thing i was stretching my ear remained in the lobe because on that object I can see a slightly discoloration
