I had a colonoscopy today and i don't feel pain but they used suction to clean me out and everytime i think about it comes back the pain but not real ?

All Pain=Perceptions: All sensations are interpreted within our brain. In body there are only afferent (outbound) & efferent (inbound) 1/1,000 second depolarizations on various nerve axons. Most embryologic development of body is driven by afferent+efferent orders from brain+spinal cord. So who is always "the expert" on all sensations? The person who perceives them, regardless how accurate or distorted the perceptions.
