My sinnuses are unbelievable. I've never seen anyone else with sinuses like mine. My condition is mainly triggered by certain foods and food additives, such as dairy, vitamin supplements, and lecithin. If I consume these triggers, My sinuses fill with gluey mucus that attaches itself to my sinus wall. Once exposed, it will fester for months after the exposure. After about 25 years of enduring this, my hearing has become permanently damaged and my sense of smell is almost nonexistent. I have not found it difficult to avoid dairy like the plaque, but, avoiding vitamins is quite tricky. Avoiding lecithin is doable, but quite inconvenient as most decent butter substitutes contain lecithin. Has anyone else experienced these problems? If so, what has helped you?
