I'm a bit worried - on my right side, if I feel right behind my ear at the base of the skull bone, and go a little further down, if I press deep there is a hard lump. I can't tell if this is bone or a lymph node?! I assume lymph nodes here would stick out of the neck, but it's not like that, it's very deep. On the other side in the same area there's nothing like that - if I press a lot, I can feel something hard, which I'm assuming is the same bone (if it's that) but it is much smaller. Is this lymphoma? Let me know if anyone has the same thing...If it's bone I just don't get how I wouldn't have ever noticed it before!
