Hi, felt sick at trade show this afternoon. chills, light headed, numbness in fingers, extreme fatigue. Went to hotel and slept 3 hours, w sweats. Woke up hungry and felt better after chicken soup, then ate a little more later. Had extreme night sweats and woke up again feeling better. Then was woken up just now by a severe case of rigors, which I ve never had befo4e. After about an hour they are starting to subside. Very scary!
