I wouldn't worry too much. I would go back to what worked for you before, the bland diet and Zantac for a few weeks. If that doesn't work, make a follow-up appointment with your GI doctor. Don't try and self-diagnose with Dr. Google, there is a lot of misinformation out there. It could be that you are just suffering from seasonal allergies. Just remember, anxiety can cause/make your symptoms seem worse than they are.
Thanks Sharon. I hope it's just the anxiety. I guess the bland diet will let me know if it's the cause or not. I have been extra stressed lately (I deal with generalized anxiety most of the time as it is).
