A few days ago i found to lumps behind my right ear, and they are tender. They are about the size of a pea doubled. Also like 4 months ago i had the same thing in under my arm pit, doctor said they were lymph nodes and no big deal now im getting worrid thats theres more behind my ears, then i have alot of discharge too but im on the pill so that could be doing that, and with that being said i have a lump on my head too the same size but not tender.
