My son has been sick for a week. Headache sore muscles sick to stomach and low fever. He has been to 3 doctors and all say he has viral flu. Hospital gave him fluids for dehydration. Now his gums are swollen with sores on his bottom lip and can not eat. Should I take him back in and see if something elses is going on? He is usually a healthy 15 year old but now I m getting worried.
HI... I think he is having stress or authors ulcers while recovering from his viral illness. I suggest you to use Byte gel and some multivitamin course after consulting your pediatrician. This is not something to panic about. Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome.
