I went to itch my belly button and my finger was wet so I looked and I have a rash where my skin overlaps. I thought it was just cause my belly button ring was covering it so there wasn't airflow but I googled and now I'm not sure. I'm currently doing a salt soak with alcohol added to see if it helps. Has this happened to anyone else?
