Can I just say that I have suffered with blocked eustachian tubes for years. The consultant wanted to insert a grommet , which would have been only a temporary remedy if at all. I refused but later my GP suggested a Beconase type of nasal spray, using it while lying on my back. I had this trouble for about 4 months last winter but I have been using an Eardoc for the last two weeks, before a severe blockage occurs and I must say the signs are hopeful. I think it is going to work for me.
