Hello,
Welcome to practo ,
I read your query and understand your concern,
According to your discription there is possibility of Viral infection so you should do atleast CBC..
If there is infectious then we can start antibiotics course...
For vomiting you should take tablet granisetron twice daily before meal...
Have dry tost or biscuits in morning before having anything else...
Have small small meals instead of taking 2 big meals...
Also you can use ginger to prevent nasea...
Hope this information helps you,
Feel free to ask further queries,
Thank you!
