You have my utmost sympathy, I have just had a rotten cold which of course left me with a sinus infection as well , until today I have been so tired just trying to breath, both nostrils being blocked, but today YEAH I can breathe again, they are not fun, I hate it when your teeth just ache and ache.

I hope the antibots do the trick for you and you will be feeling well again soon, take care and I found doing lots of inhalations did help some and I make up a water and salt mixture and spray it up my nose often, this was recommended by an ENT specialist to me.
