We were on vacation in Oregon. My boyfriend woke up vomiting, better in the morning. The following day he developed a bad headache, nausea, weakness and fatigue, and episodes of severe shaking that were frightening. When he got chills, he shook all over and his hands and feet turned white. These episodes would last 2 - 3 minutes, and happened repeatedly throughout the day (maybe five or six times that day). He also had night sweats. The next day the shaking episodes have stopped, but he is still very weak, nauseous, and has a headache (which goes away only with medication).
The doctor found nothing definative in the blood work. The shaking episodes were frightening. What could have caused that?
