My least favorite is definitely the "had this back pain for 4 years, just cant handle it anymore!" It is now 3am Sun Morning.
Name droppers also get me, especially when I am in triage.
My husband had back pain, Big man, in fetal position, crying back pain. Progressed to numbness in both feet before I would take him to our ER. We sat there for 2 hours (new nurse in triage that did not know me), charge nurse came walking by and said "WHAT ARE YOU DOING HERE?" told him, he said "why didnt you let us know you were here, we would have gotten you right back." Not my thing..... he had back pain for goodness sake!
After XRay, MRI, 3 herniated disc. HMMMM.... maybe I should have let him come in a little sooner.
