I have been running a fever of 100.6.I passed out yesterday morning and have a major headache since.It was hard to even open my eyes all the way last night. Temperature is back to normal today but my head feels like it will pop off my head from the pain.
With this limited information, the best case scenario is that this may be a bad sinus infection. The worse case scenario is that it may be an infection related to the brain or eyes. Sinus infections are much more common and much more likely an explanation. At least statistically speaking. A sound advice would be to see your doctor. After asking you a few questions and examining you, a more detailed explanation may become available. They would definitely try to rule out the worst case scenario diagnosis and let you know if you need further testing or treatment with antibiotics. If the fever continues, I am afraid you will not be in a position to sit it out. You will have to see a doctor at some point.
