I never cleaned my naval and once I decided to do that I ve faced a hard pack, it was dark and it really seemed sth that collected for years there. I tried so hard for it. then searched the internet and found I should put baby-oil wait 10 minutes then work with ear-cleaner. but that hard mass didnt come out it had pain. now the day after I asked mom and she said after birth because your ambilical cord hadnt cut well the doc burned it. and now the day after I feel pain inside of my belly button and seems oil still is there and I fear if it will become infected as I feel pain when I lay on it or touch. what should I do? should I use any antibiotics? is there anything to worry about?please guide me
