What Causes Dizziness And Excessive Sweating After Taking Nexium?

Hi, I once took nexium because of heartburn and blowting. Fifteen minutes later I felt weak, dizzy, unable to walk. I had to ask at two coworkers for help to lay me down. Suddenly I couldnt open my eyes, cannot talk, feeling like passing out. I was hearing but cannot not talk. They had to call 911, to me to the ER, and I start swetting uncontrolable. The IV went off my skin, they had to use masking tape. With a strong pain in my stomach, two hours later, I felt better and I had to stay in the hospital for four days. Diagnostic, stomach pain. I thing I was poison with the nexium. Could that be?
