Question: Here are the symtoms. first a very slight feeling of nausua followed by a full body chill. no after effects, and if is some one is talking to me they can tell when it occurs. duration of this symptom is no more than 3 seconds

It started in XXXXXXX of this year. sometimes they are weeks apart, but have occurred 11 ties in last 3 days. no, body temp has not been taken after one of these episodes. there are no blackouts, ears ringing, fingers tingling, chest pains, disorientation, loss of concentration before or during episode, loss of motor skills, or visual signs they are occurring to others. sometimes I have a few seconds, maybe 2 seconds it's going to happen. There are no smells or dark spots in my vision before during, or after they occur. No after effects. I sleep well every night. I have noticed they occur when stress levels created by job are high. they have never lasted more than 2 or maybe 3 days without a break in them lasting up to 3 weeks, and sometimes a month. This will sound funny but when they are about to stop I can "feel" somehow they are done for awhile, strange but true.
