Can a yeast infection cause swollen lymph nodes all over body?

Generalized lymph node enlargement would be an unusual presentation of fungal infections. At your age, infectious mononucleosis or bone marrow disorders are more likely causes. Autoimmune disease can be another cause. In any event, the patient with generalized lymphadenopathy should start with an evaluation by his/her physician. Appropriate testing& possible referral to a specialist will follow.
