I've been suffereng from what I thought was acid indigestion for the past four months. My doctor recently came to the conclusion that I have GERD. I have all the usual symptoms, the acid taste, the buring pain, the stomache aches at night, and a cough in the morning. He recently placed me on Prevacid, but I'm not exactly sure it's helping. It did help the first few days, but I've been on it for over a week now, and I'm experiencing some worrysome side effects. The first is that I am still constantly nauseaous and dizzy. At work if I raise my head quickly, or spend too much time sitting, when I stand I feel as though I am going to pass out. My stomach is still incredibly queasy, and I'm still drinking PeptoBismal by the bottle to keep from vomitting. Secondly, I feel almost as though I am having a panic attack. My heart races and I feel incredibly nervous. Next is the feeling that something has knotted itself up in my upper stomach. I am aware that Prevacid helps reduce the production of acid, but it feels as though a hard ball has taken up residence under my ribcage. It's not painful, just irritating. Please let me know what I should do! I would like to feel normal again, and am tired of feeling like throwing up every day! It's too the point where I am afraid to go out to eat since I'm constantly thinking of where I could throw up, or how to not throw up.
