I use brodacid on a large nipple. Today marks a week since I started taking the drug. So far, the nipple has become very swollen and the skin around has become white/gray, probably dead. She hasn't dropped out yet, but that's not what worries me. After the last shower, the water somehow got inside, and some time later, while walking, it peed from under the white layer of the medicine. I was terrified, but I guessed that somehow the water fell in there and had to come out. Today, during the bath, I did not wet this finger, and in the evening, when I transferred the weight to my finger, water peed from it again. When I was wiping my finger, I felt that this water smelled of this salicylic acid. My nail shaft area has reddened and now I'm panicking that some acid has accumulated under my skin and my finger will fall off. Should I continue to use the drug or should I go to the doctor on the spot? After gently peeling off the white layer of the drug, underneath I saw a wart broken into several sides, and in some places dark pieces of dying tissue. I'm not sure if it should all look like this.
