I did not lose sense of smell, although I think it might have changed. When I was going to a Chiropractor he said that if I ever felt like I could not feel my butt contacting the toilet that I should take action. We were thinking that trauma may have been done to the Cauda Equina (horses tail). I agree with previous poster that loss of smell should perk up the ears of a Neuro. Don't give up, I have been to three, you can learn how not to freak them out and get them to work for you. Good Luck, Ken in Texas.
