My sinusitus treatment comprises a mix of CS,Xylitol,MSM,H202,and distilled 
water with concentrated mineral in it.It works very well ;applied with a 
salvaged nasal squeeze mister.
As for tinnitus,I had it for many years ,possibly caused by working in a noisy 
environment.However in the last dozen years since I got into this Health 
food/supplement kick,it is intermittent.At one time it would be a very loud 
continuous whistling,now  it can stop competely for a short time ,but when it 
is active,the sound is mostly a soft hissing.When I spoke to my Dr. about it 
,he had no explanation.When my sinuses act up,it usually affects my ears too,so 
I use the same mix there.I don't think it is possible to completely eliminate 
the root cause of Sinusitus,only keep it under control.
