I'm close to being paranoid now, I'm scared if this is already a serious type of skin cancer or leprosy.first it was just one then it became very itchy I scratch it, it bled,I put some alcohol and cotton and ignored it, then after a year or several months I don't remember how long,I just notice yesterday it's spreading onto my feet,there's now 8 hard blisters, does anybody know what kind of skin disease is this? Please I need help. My mom just said it's an allergy I caught from our dog and won't let me see a dermatologist because she thinks I'm just being paranoid. I added an image of my feet(yes they are my feet,it's ugly right,it become dry,mostly near the hard blisters)
