I experience the same things. Everyone else it seem can smell it and they react and make their comments,but your family and the doctors claim they don't smell anything. Just yesterday,after not going out for a while,I was required to see a pharmacist beefore I could collect some medication.Everybody outside her office was coughing and sneezing and all.I knew that as soon as I left they would stop.But then I enter her office and she questions me,and then she says "I don't smell anything."
