....I cannot ethically recommend a medical treatment. However, as a lay-person, I CAN tell you about a wonderful device I have been using for the last 6-8months. I have terrible seasonal allergies about every August-October but, even worse, monthly sinus infections thru the year. I found something at Walmart called "Neil-Med Sinus Rinse"....I bought the "regular" size and soon 'upgraded' to bigger size. It is kinda gross...I 'rinse' in the shower....and don't use distilled water as they say....but the pre-packed salt and bicarb packets have kept me free of any sinus problems for the whole 8 months. In-frickin-credible. I have no stake in the company, but tell my E.D. patients about it at least weekly. I worked with an old-time nurse who used to mix her own salt solution.....and there are recepies (spelling?) on the net on how to mix your own rinse.....so try either the pre-mix stuff or mix your own and you really won't be sorry.
