The thing that took me down the rabbit hole of TMS or PPD was very shocking news. I felt a twinge in my left rib at the time i received the news. I started to feel light headed and nervous. Needless to say it sent my body into a fight/Flight and certainly a freeze state. i was stunned. From that day on i felt this twinge like someone inflating a baloon under my left rib. It would come and go. So I did what anyone else would or has done. Look for a medical cause. The more I went to the doctor the more i was determined to find out what it was. It wasn't pain (at that time) and my diagnosis changed from pancreatitis, to ulcer, to GERD to other things I can't remember. Each time I felt I was reliving some shocking news in smaller forms. The pain eventually expanded and I started to have it on both sides. Many ER visits revealed nothing. Meanwhile each E.R visit probably added more to the initial shock. I lost a lot of weight, everything hurt to eat. Even the thought of eating would cause pain and Nausea. However, this last statement was key. How could the thought or peparing for eating cause pain? If it was indeed medical and structural (which I believed it was at the time) how could imagining eating something produce the same exact pain? Hmm. This lead me down a path which took about a year to finally figure out it was all linked to my initial shocking news. I just never realized how our nervous systems are wired before. The final diagnosis was IBS or Spastic Colon. Which in my case was just a way of saying your intestines are squeezing at the wrong time with the wrong intensity. I am sure there a many many people on this site who have digestive issues to some degree. They go get check ups for H.Pylori, Ulcers, Endoscopy GERD etc etc. However how many of us ever stopped to link an emotional component? I don't mean that we were mad or sad I mean that we were in either a state of severe fight/flight or freeze. These stages can actually interrupt regular digestion. I too went down the path of seeking medical advice - which almost always said dont eat this but take this pill. To me that was all crap. How can tomato which is barely acidic compete with the acids in your stomach. It shouldn't make a difference, Yet we are convinced its our foods, not our nervous system and core issues. I had to relearn that food was safe. Which is not easy because every time I ate something I had pain. Everytime! Even prepping food was painful. It took about 4 months before the pain became inconsistent. Which is a good sign. Another 4 months before I could eat with 70% pain free. Then I went 4 straight months with no pain. How could all of this just start going away? If the doctors told me it was this or that how could it all start going away? Well for one I started doing Somatic Experiencing therapy around my initial shock. That helped a lot. But I had spent almost an entire year creating more fear and trauma around foods, believing the whole time that these foods might harm me. I had good intentions but your limbic system doesn't care about intentions. It only cares about 3 things fight/flight/freeze. I am telling this story, for one, I am having a flair up which is on and off for the last month and slowly reducing. Secondly if you already have been check out by a doc and they find nothing, maybe it's learned pain and maybe it's linked to an initial trauma or event. Third, don't create more fear around foods. The last thing we need is more fear. Four, test your self. What I mean is if it is indeed a food allergy or sensitivity or structural, just imagine yourself eating something which you believe will cause pain and see if you get pain. If you do then I would be suspicious about being truly allergic or sensitive or it being structural but rather that it's being generated by the brain. In my experience structural pain responds very well to meds and pain meds, brain generated pain has almost no response or very inconsistent. As far as brain generated pain, almost not pain killer can do much about that, the brain is a very powerful organ. Lastly just like me, learn to heal, be patient and don't add unnecessary fear when it's not needed. Im not a doc, so this isn't doctor advice it's mostly my own insight to pain. questions welcome. I had the weirdest kind of stomach pains btw. They all started to disappear without meds.
