I have been sick for 6 days with what I believe is the flu. Our entire household is sick, but I took the baby and toddler to the doctor because of his age and because of her medical history. The pedtrician said it was viral, so my husband and I have not gone to the doctor. I now have a painful bump where my tongue attaches, my husband said he had it, but it has now gone away. The head congestion appears to have gone away, but I still have the chills, sweats, sore throat, and bump under my tongue. How can I treat the bump?
