I have also had this symptom for 5 months or more, I have "moderate" encephalitis, it is one of the side effects. A spect scan will show if you have encephalitis or not, encephalitis is just a way of saying your brain is infected and swollen. Sever encephalitis can be serious and fatal. Anyhow, you should be targeting your brain infection. I finally got my doctor to agree to put me on IV next month because of this encephalitis. I can't wait, I feel like I have been wasting time on oral abx for 5 months getting no where.
