Almost two years ago, i was operated because of its pocket. After that boils heal,but a year passed it returned near the place it was operated. It happen many times that it heal but after two days it getting red again and collecting puss then it will release a discharge. By then i keep a band aid and an anti bacterial ointment on it everytime. Together i drink a multi vitamins and anti inflammatory pills. But still it doesnt totally heal. Im worry if i have a diabetes at all but i got scratches and it easily heal for three days. Please help or advice.
