I have a peculiar symptom in IBS which no doctor is able to recognize. When the motion in my bowels reach my rectum very suddenly I get a tingling sensation in my temples and I loose depth perception in my vision and I feel extremely dizzy. All these symptoms pass away as soon as I pass motion. Does anybody else experience these symptoms? This is what scares me the most and hence I do not go out of my house. Can anybody explain this phenomenon? One doctor said these symptoms look like an autonomous nervous system dysfunction. Any explanations?
