I had applied moisturizer in bellybutton to clean but got a big boil after, in nov'2021. Called a local doc for help and he only suggested Betadine powder. It got healed within a weak. But the skin inside navel become wrinkly and in may'2022 again I had a boil this time it was smaller but had blood discharge when cleaned with earbud. applied betadine powder to heal. Now again this month for the last 3 days again had a small boil inside and bleeding with pus. I am bit scared now. Is it something serious? Please HELP me doctor.
