Hello,
I know this post is late, however I was wondering if you had found out anything regarding your small neck mass? I am also a 23 y/o female and have something similar that I noticed in my neck just below my mastoid process about 2 months ago... mine is about a centimeter or so in length and can be moved around a bit; after visiting my primary care doctor I had an ultrasound of the mass and it is in my muscle. They are referring me to an ENT to have it aspirated... I'm a little nervous although my gut tells me it's nothing. Hope everything is well for you!
Hi there.
I also have this sort of 2x2cm mass just underneath where the sternocleidomastoid attaches to the skull. It has been there for years now and has not given me any problems. Possible causes are trigger points, lymph nodes, or neoplastic growth. I suggest that you observe these lesions carefully and that you should consult your doctor for any changes. Imaging studies like MRI can also give us an idea of what that mass is (if you are really bothered by it).
Hope this helps. Regards and God bless
