Hi
Welcome to the MedHelp forum!
Neck lymph nodes 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 lymphoma etc. Since this is a long standing lymph node, it could be due to dandruff or dermatitis. It is unlikely to be due to cancer. However, it is important to get this tested now, a CT scan could be most non-invasive diagnostic test. Watch the lump. Do not touch everyday but once in 10-15 days. If the lump increases in size, becomes painful, changes color, bleeds, changes shape or consistency or more similar lumps appear then note it before the appointment. Hope this helps. Do let me know if there is any thing else and keep me posted. Take care!
I also have a lump on the back of my neck near my ear. I have had it for some time now and the doctors I see are not concerned. I think it may be getting bigger (?) and it sometimes hurts when I touch it. Sorry I have nothing else, other than 'me too'
