I've had a really big increase in nausea lately. I'd say about a month or more it been off and on bad. I've also been having a cramping feeling in my lower abdomen. I also had really bad stomach acid coming into my throat yesterday. I'm not near my period so it's not that. I also know I'm not pregnant. I have other symptoms from dysautonomia but this stuff is sorta new. Any ideas of what it could be?
