i would recommend adding a yeast cleanse product to the probiotics!, the sinuses usually are misdiagnosed as all kinds of things they come up with, but they mostly have a Fungal infection! the augmentin ? helped? clear sinus? so maybe you also have yeast in gut, the probiotics are good & just add something like Solar ray yeast cleanse, i have used this product and highly recommend it too help get Balance in your gutz.
I have also flushed my sinuses with a 50/50 water & hydrogen-peroxide flush the cheap hydro from walmart i think its %3 and mixing it with water makes it %1 , i usually use a teaspoon and snort or poor into nose, you can gargle with this also!
know i must warn you if you have a bad sinus infection this will hurt/burn the first time you flush, just hangon it will go away in few minutes, as you flush more & more it wont burn any more and that infection should clear out, if it doesn't then that dentist might have to go back in and surgically remove the infected necrotic tissue.
the sweat is a good thing! it remove toxins from you, sweat sweat sweat
