For about 3yrs. I have been having some rather odd episodes. It started with being nauseous, vomiting and pain in the upper abdomen, under my left breast. As time progressed and the pain, nausea and vomiting continued other symptoms began showing up. I would become very weak and exhausted, pale, sweaty, shaky, dizzy, and swelling that comes and goes in the left, upper abdomen. The vomiting has been so forceful at times that my throat and stomach hurt. I have been woken up in the middle of the night and early mornings to vomit. The episodes are not always the same and not all of the symptoms are always present. Some days I am nauseous off and on all day, lasting 5 to 20 min. each time. Some days I have nothing and other days I will have one or more symptoms. I do a lot of fighting not to throw up but sometimes I just cant stop it. During these days I eat very little. Mostly fruits and crackers. I have not lost a lot of weight I think that is because I knew I needed to eat and would force myself to eat something, even when I was tired of eating and getting sick. I have seen many diff. specialists. I have had many, many test done. Blood test, x-rays, Scat-Scans with and with out dyes and chalky drinks, scopes ran into my stomach, a colonoscopy, and some tests I cant remember. They found nothing. Have even told my husband that it might be psychological. Sometime during all of these test I began watching everything I ate and how it effected me, to try and figure out the problem or a pattern and the only thing I have noticed is that the symptoms are worse around my period. A few days before my period I am very fatigued. I am more nauseous and it is harder to fight not throwing up. As a note, the docs. have all asked so I will include it in here. I have had my gallbladder removed.
