Sorry this is so long. I'm a 19 year old female and I've been feeling nauseous on and off for the last couple months. The first time it lasted about three days then I felt better for one day. The next evening I felt sick again and it lasted for just under a week. Then I felt better for another week or so after that. Then it was back again for a few days. Felt better for a few days. Now I'm feeling sick again. I hate it. It's always worse at night and in the mornings. I am not sexually active, so I know that I'm not pregnant. I was on medication (Nexium) for a possible stomach ulcer for about 5 weeks and then started to feel the nausea so I went off of it. I had an abdominal ultrasound about a year and a half ago, but everything was normal, so my doctor doesn't think it has anything to do with my liver or gall bladder. I am going to see her again tomorrow, but I was just wondering if anyone on here had any thoughts as to what this could be? Could it just be a weird, recurring stomach virus? Thanks in advance.
