My 8 year old is crying 😢 he doesn’t feel very good. He woke up with a sore throat and saying it hurts a lot. He says he feel dizzy. He has a fever of 99. I gave him some ibuprofen, I can’t go to the store and buy some medicine for him right now because I have a 2 years old, non mobile and non verbal with trach and vent. I have to wait until his nurse arrives for her shift. What can I give him while I wait for her to show up ?
