Hi there: I did as you suggested and notified NeilMed of the problems I have had after using their Sinus Rinse. Someone by the name of Roy called me today and insisted that the NeilMed couldnt cause all these problems as it was only salt. I told him that I had eventually googled the side effects of Sodium Chloride, which is an ingredient in NeilMed and found out that my problems could indeed, and probably, were caused by it. He was very defensive and wants me to get some advice from a different doctor to see if there is any infection in my throat. My ENT doctor has already said that my problem wouldnt be caused by NeilMed as it is only salt, but it obviously was. The ENT guy also told me that there was nothing wrong with my vocal chords but there obviously is as my voice is constantly croaky now. It never was before. I have, previously, taught Tai Chi classes for years and certainly could not teach at present with my voice as it is. You asked me to let you know how I fared. Not very well as you can see. I will be seeing my family doctor shortly but doubt if he will be happy referring me to another ENT doctor as I have been with Dr. Mendelsohn for years now. Doris Hooton korky3@***.com 416-620-****
