[|Human|] I have a lump on the lower left side of my head. It hurts a little and the tenderness is now moving up behind my ear. It is also a little numb where it is tender. I was sick for about a week and a half and my cold is now almost gone. Should I be worried?
[|AI|]  Hello! Thank you for the query. If this lump has appeared during the sickness, most probably it is a lymph node. Please note that lymph nodes get enlarged due to infection as a part of autoimmune response. Such node is usually movable and rounded. It should not be a reason to concern. Such lump can be also an abscess caused by sebaceous cyst infection. This condition appears in the area where there was a lump before. Redness, pain and swelling of this area should be present. In case of abscess you need to consult a surgeon and have it incised. If it's a lymph node you may wait and see how it will be acting. Hope this will help. Regards.
