i started having this itch around my belly button, at first i thought it was eczema because ive had acute cases of it. But, i went to go clean it and put lotion and it felt odd. Inside its open all round the top, along 2 crevices the skin is broken, and there s a hard lump which isnt open but hurts. I cleaned it with hydrogen peroxide and put neosporin but its still itchy, what could it be?
