Hi Ashley! Good evening. I am Dr Shareef answering your query. Even though this needs to be examined clinically to reach at a diagnosis, from your history it might be a boil/abscess in a pre existing cyst, which got inflamed and infected. This is an infection which could have caused rise in your body temperature (fever) leading to loss of appetite. If I were your doctor, I would have advised you a dressing of the would after cleaning, a broad spectrum antibiotic, and an anti inflammatory drug for a symptomatic relief. In case it was an abscess, I would open it up under GA followed by a broad spectrum antibiotic for a complete healing. 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.
