Hi ! Good evening. I am Dr Shareef answering your query. Form the history these bumps seem to be benign lesions, and got inflamed causing pain. I would advise you to get it clinically assessed by a general surgeon in your area with related investigations for an early diagnosis and management. Till then, you could go for an anti inflammatory along with a proton pump inhibitor drug. 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.
