<s>[INST] There is a hard lump that seems to be my spine on the bottom part of my neck. It feels like my bone. It has been there about one year. Do I need to get this checked out? I am a 22 year-old female who is at about 170lb. I am 5 foot 3 3/4.  I have a history of migraine and pvcs. [/INST] Hi, dear thanks for the query to my Chat Doctor virtual online clinic.It's my pleasure to help you. My diagnosis -This lump-mostly due to the Normal protuberance due to spine of Cervical no.6 vertebra, as it is hard lump for a year, which you found / noticed by accident a yr back. If no problem with it and if it's not growing and is stable, then don't Worry. Your PCs and migraine don't have connection with the spine lump -as it's a NORMAL C-7-spine. Still on safer side I advise you to Consult an ER Surgeon.Don't worry and act fast. This would solve your worrisome query. Hope this would solve your query. Wellcome to my Chat Doctor clinic once again. Have a Good Day. </s>
