question: 17 MONTH OLD, teething 4 molars erupting, had high fever and some vomiting for 3 days, (other children are having similar) but this one has one quite enlarged gland under L jaw area, seems slightly tender to touch, no fever now, not hot in that area. Child is mostly better from the flu, walking, sleeping well, no vomiting. has been to Dr x2, but he never checked the glands. Is there something to give child or do, or just wait several days to see if swelling goes away?
