And if you dissect the term IBS, what do you get? "Irritable Bowel Syndrome" . Which is not a real diagnosis that comprehends an actual pathological process - it's just words that describe the symptoms. The medical establishment came up with this phrase to make their patients feel like they were getting a diagnosis, but the truth about IBS, and many similar so-called "diagnoses", is that it has these components of the stress-based condition we call TMS:
1. There is no clear cause even after decades of research
2. There is no treatment that results in a cure
3. The only recommendations are to try to mitigate symptoms and "live with it"
4. Symptoms fluctuate and become worse with know stress triggers.
Look, this isn't your first round of symptoms - yet I don't really get a sense that you've seriously incorporated "the work" even though it's been brought up by and to you since you first joined. It occurs to me to point out a basic issue.
The primary condition that affects all TMSers is anxiety. Anxiety must be addressed methodically, mindfully, and perhaps even therapeutically. Without seriously attacking anxiety, relief from the physical manifestations of TMS will be difficult, if not impossible, to achieve. Fortunately, unlike IBS, we absolutely do have effective treatments for anxiety.
The first thing I recommend is inexpensive and easy, which is reading the little book that has saved literally thousands of people worldwide since its publication in 1969: Hope and Help For Your Nerves, by Claire Weekes PhD.
Good luck.
