IBS and horrible shaking

[rlc1962]

I'm 54 years old. For the past 25 years, I've had acid reflux issues and was on Prevacid or some other type of prescription medicine to help. The acid was starting to cause my throat to get really pink so my E.N.T. highly recommended that I see a specialist to get a Nissen Fundoplication. Which I did. And honestly, it didn't hell all that much. Within the last 3-4 years, I started getting really really bad lower abdominal and intestinal pain from time to time. I don't "go" as often as most. I discussed this with my doctor and she said I most likely had IBS. Once or twice the pain was so bad, she prescribed Xifaxan. And that worked like a charm. Around 3 years ago, I had an attack that came on where I got very dizzy and felt even disoriented. My heart started racing. And even started to shake uncontrollably. Arms and legs. That episode lasted about 30-45 minutes. I was at work at the time so a co-worker had to drive me home. I wrote it off as food poisoning at the time. It happened again about 9 months after that. Then again 6 months after that. And it is increasing. Every few months. This week, it happened TWICE! Two days in a row.  Every time this occurs, I also have a lot of gas swirling around in my intestines. Making all sort of sounds. I've discussed this with not only my primary doctor but my Gastro doctor too. I get upper endoscopes every few years because of my history with acid reflux and had my last one last Spring. No real issues or polyps. My stomach was also slightly pinkish in certain areas.  Here's my question, what if anything can I take to stop this from happening? I have to get a handle on this. What in the world would cause your body to shake like that? When it happens, it is quite scary. I'm talking with my doctor again about it this week. This has to stop.  Thanks in advance for listening and for any advice.
