Hi, I have abit of dental work done, had 4 top front teeth removed, I now wear a denture, and since this removal, my nose feels blocked, when I breathe its normal but when I try and blow it, nothing comes out, occasional thick clear snot comes out, I feel light headed sometimes, and unable to concentrate, doctor said sinus problems, also when I wear my glasses it feels so heavy on my nose. I just want to feel normal again. Thanks
