As I stated in the very first post, they are just lymph nodes. Don't worry about them. I have it behind my right ear. DO go to the dr asap if they change in size (get bigger). :-)
Since you don't have any symptoms it may be cysts. I would get them checked out though.

Never experienced any of those symptoms - they're just ... there :/
Do you have any symptoms? Any pain in the ears or behind the ears, dizzyness or vertigo or any other symptoms. It could be a benign tumor called an acoustic neuroma but you would need an MRI to check.I suppose it could be a cyst as well. Cysts are more common.
It is a lymph node that probably gets bigger and smaller when you are about to get sick. Larger, that is, when you are going to get sick.
