If it is near the back of your earring, you might be having an allergic reaction to the material that your eraring is made of. I have this happen to me as well. I can only wear nickel free earrings. Just take your earring out for a few days and the bump should go away.

It is most likely a large pimple.
It is better to see a doctor to know what is that bump, if it is painful then probably it is an infection which must be diagnosed and cured as soon as possible. If the sweeling or the bump is not at all painful but it grows fast or becomes bigger, it might be possible that it is a cyst and it needs to be removed as soon as possible. I advised you to see a doctor really.

A small, painless bump behind the ear of a child can be many different things. Some causes of this include mastoiditis, dermatitis, swollen lymph nodes, sebaceous cysts, cancers, and parasitic infections.
I went to the doctor today to see what happened. Turns out I was allergic to the earring, so if this happens to you, you should buy 24karat gold or plastic earrings. My doctor also recommended fucidin ointment which costs about $20. Hope this helps :)
The best idea is to talk to your doctor.
I would call a doctor and see what s/he says.
A bump on the back of your head where the occipital lobe is located could be due to several reasons, such as the natural shape of your skull, muscle tension, or inflammation from conditions like occipital neuralgia. It might also be a benign growth, such as a lipoma or cyst. If the bump is new, painful, or accompanied by other symptoms, it's advisable to consult a healthcare professional for an accurate diagnosis.
