8 years ago I developed a mysterious set of symptoms all over my body including heart palpitations, trouble breathing, chest and stomach pain, impaired concentration, cold tingling hands, feet and lips, tremors, muscle twitches EVERYWHERE, gastro intestinal problems, insomnia, and tinnitus. I had no actual weakness. I had an MRI of the spine and head (MS and Gullian-Barre), EMG tests (ALS), and tests for lymes, B-12, heavy metals, and ulcers. They could find nothing wrong with me and I was diagnosed with Generalized Anxiety Disorder and BFS. After some psychological visits and treatments with Zoloft I started to get better and mostly stopped believing that I had a neurological disease although I still had random twitching around my body sometimes. Recently while I was training for a triathlon I noticed I had an occasional extra heart beat. I ended up in the ER because I developed a full on constant extra heart beat with every regular beat. At the ER they could find nothing wrong with my heart. I went and saw a cardiologist who performed echo cardio stress test and was told that my heart was strong. I went on beta-blockers which got rid of the extra heart beat. Anyway, I couldn't get it out of my head that something was wrong with my heart and then I started to have other symptoms: chest/upper abdominal pain, heart palpitations, cold/tingling hands and feet and face, trembling, muscle twitches, burping, gastro issues, impaired concentration, tinnitus and anxiety...sound familiar? Now I've started thinking I have ALS or MS or cancer or something, but my doctor suggested that I might have Chronic Hyperventilation Syndrome. When I started reading up on it I could not believe that I found something that matched my symptoms. I started on Zoloft again to help with the anxiety, but I have this terrible fear that I have something worse. Should I still see a nuerologist again to make sure I don't have MS or god forbid ALS?
