I had started this towards then end of my bought with bronchitis. which I never had before and what my doctor called it, after he ruled out swine flu. I do not smoke or drink and I am a hiker. I noticed allot of similar symptoms here. dull pain to sharp, to driving thru from front to back, burning, twitching, hard knot feeling, bloated, yes I have been having them. saw two doctors, blood tests, xrays, they have guess from a bacterial infection, to a muscle pull to IB to some kind of virus. non of thier acid reducer, muscle relaxer pills help. Only heat does. it isn't on my rib but up underneath it feels like. I have had a kidney stone before, it does not feel like this. anything can set it off, food, stress, pressure, activity, it never really goes away. isn't it funny how our so called educated doctors and all our hi tech tests cannot seem to find out what's wrong or cure us. It fakes us out, we think it is going away and comes back. I am thinking maybe, pollution related, contaminated water, food products, look at all the food recalls, from plastics to metal being in our stuff... and what about bio-terrorism? make all the Americans too sick and in pain to fight back, infect the nation. It is just plain ODD, that no tests show anything, Doctors are grasping at straws.. and these symptoms can be so many things, yet most of us are still not properly diagnosed or cured. It could be as simple as something we are ALL consuming.. maybe in water, in soda, in milk? or eating, or breathing.. I dunno..why are so many of us suffering and all the doctors and tests are just a waste of money?? and yes Stress and Depression will make anything worse..duh! but that is NOT the cause. I think the FDA needs to start testing ALL our beverages and food products for contaminates. We have already had baby formula recalls, pet food recalls, even medicine due to metallic pieces, all this can cause terrible havoc on our bodies and whether it is just because of a lack of quality control or intentional..the medical community needs to start thinking outside the box, because this problem is very widespread all over the internet forums, and any time you have something invading you body, flaring up organs and intestines, these can cause damage to things and appear to be a disease, but I think there is a bigger picture here. something...is contaminating our bodies and raising havoc, maybe not deadly, however it could be after damaging organs after time, because if you read all these and others, our symptoms are 75% the same but we all are blaming it on different activities etc, strange so many people are getting this and no real answers, but what is it we ALL do that is the same...??? we EAT and DRINK. and we all are getting pain in the lower left rib area. my doctor probably thinks I just want drugs, since tests are showing nothing, and I hate medicines period and I am not regularly on anything, but occasionally due take headache medicine. but this pain has made it nearly impossible to sleep, work, or relax. it is REAL. and I cannot afford any more tests with no conclusions. This is STUPID.
