My husband recently noticed enlarged lymph nodes around his neck and ears, one of which is so large you can see it out of his neck.  He was doing construction work in our basement this weekend and came in contact with a lot of sawdust...can that cause a reaction and make the lymph nodes go crazy?
Hi, Welcome to Chat Doctor, This swollen neck could be due to infection or allergy of the neck lymph nodes to this dust exposure. Lymph node swelling could be due to viral infection (EB virus, adenovirus) or bacterial infection or parasitic infestation (toxoplasmosis) or allergic etc. He must be evaluated for routine blood counts and lymph node biopsy with thoroughly ENT examination by specialist. Treatment is required like antibiotics (accolades, quinolones or cephalosporins) with analgesics, antiinflammatory and antihistamines with other supportive treatment. You must see an ENT specialist or surgeon for further advise. Thanks and regards,
