I was treated for my asthmatic condition by a nurse practitioner at the student medical center of the university. I usually get prescribed for "nebulizing treatment" by my usual doctor at the med center when my condition gets worse, and it has always helped my breathing get better. But this time [I don't know if she changed the dosage/ the type of medicine to input the nebulizer] my breathing got really worse that it went from 98% to 72%. and when I asked her to treat me for my acute breathing condition right then,she acted very ignorant and asked me to take the medication she prescribed and told me to just go to the emergency unit if it gets worse. But my student insurance doesn't cover the "emergency" conditions. Is this a possible ground for suing the NP and the med center?
