Good evening. I am Chat Doctor 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 Chat Doctor.  </s>
