It sounds like you might just have been worrying yourself sick. It can happen. Maybe it started out you had a virus or maybe you were stressed back in April, and you got physically sick, and then you started worrying about getting sick again, and worrying and thinking about it made you feel sick. (This is how I caused myself to suffer random stress-diarrhea through half of middle and high school. Self-spawned anxiety is terrible.)
I always get a little nauseous while on vacation as well, and sometimes it lasts the whole trip. It's the stress of being in a new place, or travel. Flight, especially. You might have an anxiety disorder perhaps.
Also a note from experience, my sister is prone to panic attacks. She takes medication to prevent them. For a couple years in college she was convinced she had ulcers because she had chronic abdominal pain. She saw a lot of doctors who all said she was clean and perfectly healthy until someone finally prescribed antidepressants. She doesn't have those problems anymore, with the medication, although she still needs valium to deal with flying in planes.
Just a quick update. The nausea seems to only last about 10 minutes then it goes back to a low level i tend to not notice as much. Maybe im having a virus of some sort
Couple days. It was severe tuesday and wednesday mild yesterday and even milder today
Yeah I had similar issues, still do but not like a week ago, how long has this been going on?
