A swollen gland can occur when you have an infection or virus (even something like a very mild cold). A sebaceous cyst is basically a clogged hair folicle.

thanks for your response. what causes a swollen gland or sebaceous cyst?
Hi and thanks for using the forum.
Your friend should have the lump checked out by her doctor. The pain may be related, but I cannot be sure. This could be a swollen gland, a sebaceous cyst, a hernia, or even a muscle pull among other things and should be evaluated. Good luck.
