Here is my story, maybe it can help someone here. I know everyone is different... but this can help...In Jan I caught the flu which ended with a sinus infection, for which I was given antibiotics (a known cause for IBS related symptoms). Once the sinus infection was gone, I felt better... but only for a few weeks.For a month I was naseaus... the entire month of Feb, I got nauseous after EVERYTHING I ate... but I never figured out why... and it just stopped. For a few days I felt fine.Then, I was getting a sharp pain in my right side that knocked me to my knees... this happened several times a day for about 10 days. It only lasted a few seconds each time, though. Then after the 10 days, that pain stopped, and that side of my abdomen was very sore... sore to the touch with rebound pain. The Dr thought it was appendicitis or ovary problems... it wasn't. I went for an ultra sound of the entire body cavity... nothing was found... then that day, after eating, I experienced the most horrible feeling ever:You know when you throw up, your body goes through a process of beginning to throw up... but before your body makes the decision to officially go into vomit-mode ( as I like to call it ), your blood pressure drops, but you're hot and cold at the same time... you want to panic but your energy is gone... you just feel like you're going to explode... This is the feeling BEFORE vomit-mode, BEFORE you see relief in the near future... well, I was in this state for about 17 hrs strait! All I wanted to do was go the the bathroom (number 2) but I couldn't get up... being upright was going to kill me, I was convinced.After a few days I felt better. And 2 weeks went by with no problem, other than my fear of eating, since I didn't want to make myself sick again.Then the entire process started all over, but this time it only took 4 days to go through it all. Luckily, I got sick (like I just described) IN the doctor's office... so he got to see it all. I hadn't lost any weight, I was still going to the bathroom regularly (although more frequent than most people), but I didn't have any other symptoms, other than constant fatigue... so he didn't think it was anything life threatening. He prescribed clidinium, a relaxant and anti-spasmotic... it was helping, but only with the nausea. I was even more tired and the spasms were still there on my right side.I tried adjusting my diet, that didn't really help. I tries eliminating stress... I was relaxed, but still sickly.Then I saw a Dr who used "Applied Kinesiology" on me. That is when certain muscle groups are tested to see which specific organ is malfunctioning. He decided that my ileosecal was staying open, this is the valve that connects the small intesting with the colon. This is the problem. The antibiotics stripped my small intestine from the bacteria and enzymes needed to process food. That valve is controlled by secretions of the stomache, the chemistry of the small intestine, and emotions. Since it was open, the food that my body was unable to process went straight throught to my colon, and at times would freely move back into my small intestine as waste. This was what made me so sick.The Dr gave me probiotics to take after each meal (to replace the good bacteria needed in the small intestine), spanish black radish to take after that (which sooths the digestive system), I eat a spoonful of Dannon plain yogurt after that, then after one meal a day I drink a few ounces of buttermilk. There were also a few things I needed to cut out of my diet for 2 weeks. This things are putting the right things back into my digestive system. After the first day of this, I wasn't tired! And now, a week has gone by and I'm not sick!My suggestion is that you find either a medical doctor OR a chiropractor who is trained in "applied kinesiology" and see if they can help you.I hope this helps someone. Sorry if it was too long.
