Hi, my son has been diagnosed with LIP, CVID, and a host of other pulmonary/cardiac issues -- He is also ig-a negative. He has been treated for bronchitis for about 2 weeks with augmentin, but today he has started vomitting phlegm and says his stomach hurts, his overall demeanor is tired, and he has no appetite. I'm not certain if I'm seeing the start of something worse, or the beginning of improvement --wondering if I should take him to our base ER.
