My son has been sick for 5 weeks. Week 2 was put on a steroid that didn't do anything. Week 3 was told to take him to ER (2nd time) where they did absolutely nothing. Week 4 saw his dr again and she prescribed zpack which he had been done with since Thursday. Picked up a breathing treatment machine and been using it since Tuesday on him. And the only thing that seems to be better is his coughing. He still can't freaking breathe, so he is aggravated and wants to sleep 24/7 and not eat but maybe every 7 hrs which is NOT normal at all for him being that he normally eats atleast every 3. It's frustrating for me too bc I cannot do ANYTHING, I just have a baby whining and crying 24/7 unless he is asleep. I don't know what the hell to do! 😭
