I have bad allergies to everything, expect nuts!! I suffer with sinus problems which are out of control. The mucus is what is worse. I don t do dairy and have air purifier. I started the allergy shots that put me right back to the worse point of suffering. Had to go to urgent care, put me on Prednisone for mucus and sinus cavity. I cannot continue this vicious circle. Tried Serrapeptase(enzyme) to breakdown protein that cause mucus. Works okay, but I want to be mucus free!! Not big on Pharmacia, prefer natural/organic way to beat this. Any suggestions??
