What is the age of your son?
What were his symptoms? Did he have fever or ear discharge?
What was done for his ear infection?
What were the problems going on for the past 8 weeks?
Please feel free to get back with all details.
How ever, from what you have mentioned, he has ear infection, tummy ache and few episodes of vomiting
. It may all be due to virus.
is given to stop vomiting. If he says his tummy hurts too, if in the upper abdomen, it might be due to gastritis
associated with the same virus. In that case, he might need some drugs like antacids or lansoprazole
according to his weight.
Are you giving him any other medications like antihistamines? In such a case the lethargy
may be due to that. How ever, if his activity is very less and his intake is poor, its better you have a word with your doctor and have him examined again to rule out any other major problems.
hope my answer helps you.
Wish a speedy recovery for your kid.
