For a the past two days now I have had some odd symptoms and not sure if it is associated with GERD/Acid Reflux? I get really lightheaded and dizzy followed by nausea and heartburn. I also do have bad anxiety and not sure if that is playing a part in it as well? I keep feeling as though I am going to pass out and be sick and it is really freaking me out? Do you think it is being caused by gerd/acid reflux, anxiety, or could it be that I am getting sick? Please let me know. I can't stop freaking out.
