Woke up at about 7:30 and was super nauseous, and a nasty headache. Fever picked up really fast. Was sweating massively and hyperventilating. Fast heart rate. Went to the ER by about 11ish.
They did x rays, CT scans, all kinds of blood tests, and found no obvious source (even going so far as to say that everything looked "great").
It wasn't until yesterday morning that I got a call from the hospital saying that my tests came back positive for a blood infection. Then told me to get back to the ER ASAP.
