My Husband Went To The Doctor This Week Due To

My husband went to the doctor this week due to extreme crotch itching; and was diagnosed with yeast infection. He is using Lotrimin, as directed by our physician; and now (3days after starting the medicine) has swollen testicles so large they look like one large testicle. Discontinue the Lotrimin? Return to the dr?

Help! He also has a script for Nizoral, which hasn't filled.
