Two weeks ago my son s bellybutton had discharge in the form of pus mixed with a bit of blood. We went to the doctor who cauterized it and it bled older, faint colored blood and no more pus. It bled very little each day...one discharge per day, for example. It s been like that for one week now, very little, blood with a faint, older tinge.We began treating with antibiotic over the counter drops and the bleeding has subsided substantially to now a faint, older tinged color of blood. No pus, no swelling, no fever, no loss of appetite and normal behaviour.I am curious if it s a subacious cyst and what else can we do.
