Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain it seems that you have infection around the belly button site leading to the symptoms that you are experiencing..
As belly button is the area where there can be accumulation of sweat and debris and it can lead to bacterial infection and cause
redness, lump formation, pain,itching and burning..
I would suggest you to consult a General physician and get evaluated and in case of infection you will be advised to take antibiotics like
Ciprofloxacin, anti-inflammatory painkiller like
Naproxen, clean the are with antiseptic liquid and apply antimicrobial and
steroid ointments..
Keep the area clean and dry..
Hope this information helps..
Thanks and regards.
