Eczema Treatment Care

My lips are swollen, raw, crusting…. Sometimes the skins on my lips turns white then sloughs off in a seemingly never-ending cycle.
I can’t eat normally and everything I drink has to come through a straw.
I have been to several dermatologists and had 2 seperate biopsies. Those results were normal and as well as bloodwork. I have shown an immediate sensitivity to cinnamic aldehyde through a patch test and I am being treated with topical steroids. I have also eliminated all toothtpastes, gums, and mouthwashes from my routine. After many months I am still suffering and need answers….. Is my condition really a result of cinnamic aldehyde or is there something else going on? Will there be any relief for my condition ??? Does any one know anything to help me??
