My sister is 34 years old and for the past few days has had a constant migraine, tooth pain, fever, cough, nausea, vomiting, and mouth sores. Her current medical conditions are as follows diabetes, polycystic ovary syndrome, GERD, osteomylitis, and a gallbladder removal 3 years ago. She currently has no insurance so she does not take the meds prescribed to her. I would like to know what could be causing her current symptoms and if I should take her to our local ER. Thank you for your time
