[|Human|] I am a 5ft 8in 135lb 35 year old female. I have unremarkable health history aside from minor gynecological issues, and migraines about twice a week. Today I found a pea sized lump at the base of my skull on the right side just at the hair line. It is tender to the touch and not movable.
[|AI|]  Hello! Thank you for the query. This lump might be a lymph node which can be there as in normal conditions or some benign skin lesion like sebaceous cyst or lipoma. It is hard to tell not being able to palpate it. Please consult your doctor with this lump and have an ultrasound. In case of enlarged lymph node biopsy should be considered. Lipoma or cyst can be removed with small incision. Hope this will help. Regards.
