Hi ! Good morning. I am Dr Shareef answering your query. From your history it seems that you have got a boil with surrounding cellulitis over the area. If I were your doctor, I would advise you first for a blood sugar estimation to rule out any chances of Diabetes mellitus and treat it if positive to control the infection. If the swelling is increasing inspite of the antibiotic, and little amount of pus has shown itself up, there could be a deep seated abscess which would need drainage. Therefore, I would refer you to the ER of the nearest hospital or to a general surgeon, who would do the needful possibly under some kind of anaesthesia. This would relieve your problem and the antibiotic would be able to act better on it after drainage. Till then, you would have to continue your antibiotics with some anti inflammatory drug with a proton pump inhibitor for a symptomatic relief. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you an early recovery. Dr Shareef
