Hello. I Developed A Sudden Very Tender Nodule Yesterday. I

Hello. I developed a sudden very tender nodule yesterday. I had my husband feel it and afterwards had to take two Aleve to soothe the pain. It is near my upper vertebrae, right side, just below the back of my neck. I tried to call my physician earlier today, but his hours are my work hours. I haven't experienced this kind of
situation any time previously, but do have prior neck injury from auto accidents.
