I recently had a flu-like virus, and when I was nearly recovered, I developed a sore spot at the back, left hand side of my head, which then became swollen and painful. It lasted a few days, and then went away. However, four or five days later it has come back. It is constantly painful - feels like constant pressure, and the whole area is swollen and sore. I was wondering if it could be a swollen lymph node. If it doesn't get better, I will see a doctor on Tuesday, but was just wondering if anyone else had had this?
