Hello,
I can understand your concern. There seems to be one of two possibilities in case of your son.
Firstly, it is possible that the child has viral infection which is presenting as
low grade fever, white areas in mouth and on lips and pain in stomach. Usually, viral infections heal by itself as the body's immunity takes over in 7-10 days and it is not treated by medication.
Secondly, there is a chance that the focus of infection is in the stomach. Stomach infections are able to develop ulcers in the mouth that are painful. As the stomach infection will heal, the mouth pain will disappear. Stomach infection might need treatment with antibiotics.
In addition, there is also a possibility that the mouth and stomach problem are different and coincidental and mouth problem is associated with another episode of
fungal infection.
To conclude, I would advise you to visit a
pediatrician and pedodontist for clinical examination of the child and further investigations, if needed. I hope this information helps you. Thank you for choosing HealthcareMagic. I wish your son feels better soon.
Best,
Dr. Viraj Shah
