For over 3 1/2 years (since I had my daughter) I have dealt with a range of symptoms : brain fog, feeling "off", feeling dizzy, feeling like im gonna pass out (eyes are dilated when this happens), heart palpitations, tingling, numbness, Panic attacks with tremors, cold, night sweats, leg cramps, belching, feeling of doom. I was scared to be alone with my infant daughter, thought I would pass out! I noticed my symptoms would ease after a bowel movement (in which my head would tingle every time). Been to ER numerous times...told every doctor same symptoms. ....had CT, MRI, bloodwork, heart monitor, endoscopy, Hpylori test, SIBO test, celiac test, tried Nexium, tried gluten free diet...all negative and still sick. It wasn't until after I wore the heart monitor and was told by a heart doc that my heart was fine that I stopped having panic attacks with racing heart. I swore my doc thought I was crazy so I researched on my own. ..and thank God I found a forum where this guy thought he was allergic to corn from the time it entered his body til the time it left his body he was sick. I called my doc asked for a food allergy test and thank the good Lord I have my answer! I am allergic to SOY!! Pregnancy changed my food allergies because I was not allergic before. It is very hard to avoid because soy is in everything but I have not had symptoms since I have been avoiding soy!! I definitely know if I slip up and eat something with soy!! I hope my post helps at least one person because those symptoms are truly debilitating! It was the post of another that gave me my life back! God Bless!!
