I've never taken the Nexium before myself, but I just did a fairly extensive search and I'm not finding anything that matches your symptoms. Don't get me wrong - I'm on your side and was looking for things that could go wrong. :) Usually when you put a drug, or a health issue that has been causing major problems into a google search, or yahoo search engine, it comes up automatically with lawyers names! lol I found on the "Nexium" site that most frequently reported adverse reactions were headache, diarrhea, and abdominal pain. However under the physician site I did get a better view and it lists the adverse effects that occur in, I think 1% of the population...it's way too long to list here, so I tried to copy and paste the address and it wouldn't work, so here's the address hand copied and I hope it works. Remember, one thing that I've been told and read. These drugs were initially made and prescribed for people taking them about 6 wks. So with us 'long-timers' (another made up word -I know Jen loves those! ) I suspect we could come up with a few extra symptoms. I wish you the best of luck, John!!
