Can we give him Tylenol/Advil for this? Is there anything else we can do?

Yes, it is recommended to give Tylenol or Advil for pain and fever relief. In addition to that, using HydraSense saline solution can help with congestion and reducing runny secretions that can cause coughing. If symptoms persist for more than a week or if new symptoms such as fever or colored secretions occur, it is advisable to consult a doctor.
