I wish I could just delete some of the last messages and then post something that makes more sense than hundreds of posts. --- HERE is what I think should be on a sticky on this post ...
1. NO ONE in their right mind would use the standard tips from a Water Pik, as anything close to that pressure would certainly bring horrible pain!
2. There is a specially made tip that will NOT blow anything out, nor will be a force that will hurt at all. Write to me and I will find the manufacturer, or search it out on the web. As I recall, it was about $10, or you could figure out how to modify a tip yourself.
3. ANY pain should NOT come from the solution. IF it does, you have your formulas wrong. Here is what I KNOW WORKS and is NOT PAINFUL.
A. Use 1000 ML of COOL WATER - warm will HURT (I know, this sounds crazy.)
B. Use 1 and 1/2 TEAspoon (equal to 1/2 TABLEspoon -- ?? ML) of NON-IODIZED salt (Iodized WILL HURT)
C. Use 1/2 TEAspoon of Bicarbonate of Soda
D. Add less than half the water to the container, add the dry ingredients and swish til clear -- IF you don't totally dissolve the salt, and you have undissolved salt in the bottom of the container, your first use will provide concentrated saltwater that will feel like it is burning your nose out! Fill the rest with cool water. Use it within a day or so... (Keep in mind that you could grow nasty things in that water if you aren't careful).
I've been using this only when I have a cold, and it really has helped me over the past 10 years. When I researched the subject, I found that many people with sinus problems have been "cured" after decades of trying everything else, including surgery.
I use a "good model" water pic, that has a large container, with a variable pressure, and with pause, built into the handle. My only complaint is that the plastic hose eventually becomes brittle and breaks.... (due to salt water?? Is that why you have to rince the BCDs?) Water Pik sells a replacement hose and handle for about $10, delivered.
I hope this is comprehensive enough to make a sticky, and save everyone a lot of time. If not, try to edit / improve this until it can "stick" around.
