It began with a severe headache just under my scalp/skull on top of my head. Then my temp climbed quickly from 96.4 to 103.4 (my normal is 97.5). It stayed over 103 for hours before I went to the ER. My only secondary symtoms were extreme fatigue and muscle weakness. Also bright lights and sharp noises seemed amplified by 10. I did not have any chest pain, sore throat, runny nose at all. When they examined me, my lungs sounded clear. Although I did not have a painful neck, they suspected meningitis. After simple blood and urine tests showed zero abnormalities, then then did a CT scan of my brain, which showed no swelling. They then did a spinal tap to draw spinal fluid, but it also showed no signs of elevated proteins, white blood cells, etc. They have sent 3 vials of blood and spinal fluid off for culture development. That was 4 days ago, and I still do not have the results. They dismissed me, so I saw my primary care physician who heard a wispy noise in my left lung, so she was sure I had pneumonia. I still have no chest pain, sore throat or any respiratory symptoms. I am taking Levaquin, but have no idea if they are on the right track. My fever is held in check by taking ibuprofen every 4 hours, along with Tramadol for the headache. Any ideas ???
