I have a hard, non-mobile, lump behind my ear, the size of a pea. It is directly behind my ear on my neck just above where my lobe stops. I believe its in my lymph nodes. I have had some tooth pain due to a wisdom tooth. I am 37, high anxiety, not overweight, normal dr. visits. I just noticed this bump two days ago. Should I just wait for my dentist appt. for removal of the tooth, or should I see my family dr.?
