Feels like two permanently swollen lymph nodes, just on left side of neck. One under jaw, other lower down neck. No pain, but always there. Reasons?

Cervical Lymph Nodes. Enlargement of the lymph nodes in the anterior chain of the neck can be a sign of active infection or occult disease. Non tender but enlarged lump nodes in the neck may be reacting to infections drainage from the head and neck including mononucleosis, &HIV disease. Lymphomas may present with non tender lymph node enlargement. Consider a head and neck exam and maybe antibiotics and needle biopsy.
