Thank you for posting your query.
Though we need to examine you to come to a conclusion regarding the lump at the back of your head, one can be sure that it is not because of your repeated cracking of the neck.
The possibilities include lipoma
(or other benign tumors), sebaceous syst and an abscess
Please consult a general surgeon
for evaluation, diagnosis and treatment.
