Thank you for the input.
Cough with fever suggests a respiratory infection.
His respiration rate is a little higher.
An infection of bronchi/ lungs needs to be checked for.
Groin pain, swelling can be from a local inflammation, infection, lymph adenitis, muscle pull.
Tepid water sponging can be done now.
If the temperature, breathing rate do not come down, I would advise to take him to urgent care or ER.
Otherwise, you can take to his regular doctor.
You can give motrin after an hour.
I hope this information will be helpful.
If you have any query, please feel free to ask.
