I’ve had it before... It’s really devastating and for me the worst part was the inability to think straight or coherently for very long.
Thank goodness for the Internet and a Physician’s assistant that knew the symptoms and the Doctor he worked for listened to him and trusted his diagnosis.
A treatment of the right anti-biotics and I was on the mend three weeks later and fully recovered in about six months.
Sounds like my experience last summer, but my doctor insisted the cause—wasn’t the black fly that bit me—although I had ground the black fly into the bite. Also the exact site of the bullseye.
