Hi! You probably have a boil or abscess
on your ear lobe. Neck <span style = 'background-color: #dae8f4'>lymph</span> node
s can be the result of tonsillitis, pharyngitis (infection of upper throat), infection in mouth, caries in tooth, internal ear infection, outer ear infection, eczema, dermatitis, dandruff, breast cancer, fungal infection, other cancers like lymph
oma etc. If you had flu like symptoms initially then it could be due to infectious mononucleosis too. In your case in all probability it is the outer ear infection.
