For the past three weeks or so, I have been having lower abdominal cramping that makes me both nauseated and also with the feeling that I need to make a bowel movement, even when I really don't. It's not menstrual--I haven't had my cycle in nearly five months--I'm not pregnant, I've just never been regular in them. I have also noticed that I am not hungry as often--normally I would eat three full meals a day and snack in between, but now I can hardly finish two meals a day.
And even when I've eaten, I get this sort of tingly sensation through my stomach and esophagus (you know, like how you feel when you haven't eaten all day). I've also been getting acid reflux a few times a week from anything carbonated or with the slightest amount of spice to it.
I haven't changed anything in my diet. As far as lifestyle, I did recently begin a new job, but these symptoms are far too physical to be in a psychosomatic manifestation, or whatever mental blame one might suggest it to be.
(Also, if it is relevant, I am 21, female, caucasion.)
