Hello,
Welcome to Healthcaremagic.
From your query i found that you are too much worried about constant oozing from
umbilicus (Belly Button).
Possible causes could be
1. Urachal cyst
2. Fungal infection
3.
Diabetes.
4. Patent urachus
5. Bacterial infection.
Urachal cyst is common, if ti is not cleaned properly lead to infection
Urachus is tube connecting bladder and umbilicus when we are in womb.
If it is patent, get infected and cause oozing of fluid.
Follow these measures.
Wash and clean the affected area.
Try not to keep the belly button area warm and moist as it will support microbial growth.
Resist the urge of itching.
Antibiotics are needed for bacterial infections.
you need to some investigations like CT and
MRI scan to know the extent of disease.
Hope this helps.
If any doubt, Please reply.
Take care.
