Baby almost 5 mos has goopy left eye I think clogged tear duct but also congested and has lump behind left ear on head. Lymph node? Thoughts?

Appt time. The baby can have bacterial conjunctivitis, to nasolacrimal obstruction, viral infection--he/she really needs to be seen. As far as lymph nodes the one near the ear is located inferior to the ear not behind it.
