[|AI|]  Hi ! Good evening. I am Chat Doctor answering your query. This could be because of inflammation due to sitting on your butt for a long duration. If I were your doctor, after a clinical assessment of yours, I would advise you for a broad spectrum antibiotic, an anti-inflammatory Chat Doctor.  If it persists or increases, I would refer you to a general surgeon. 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 Chat Doctor to clear doubts on your health problems. I wish you an early recovery. Chat Doctor.
