I recently found a very deep lump on the back of my neck on top of my spine and extending to the right. At first I thought it was a muscle not because I noticed it while sitting at the computer for a long time doing a project and it began to hurt. It has not decreased or increased in size within the week that i have noticed it. I am having some tingling sensations on top of my shoulders, and am guessing that this is related. I am quite nervous about this, and am beginning to think I should go to the student health clinic at my University, but doubt they will be able to tell me much of anything except its a swollen lymph node. I have never had a lymph node swollen this big, or in this part of my neck, especailly not one that causes tingling sensations. Has anyone ever had a lump such as this? If so, was it just a lymph node or a cancer or just a cyst of some sort? I am young and healthy, with little family history of cancer. I am nervous. Should I be?
