I hit my head on the beam going down from attic and have no sense of smell or taste for the last 4 months. When, if ever, will I get those senses back. I can sense the difference between sweet, sour, bitter, spicy but have no idea what the actual taste is. I have no sense of smell of any odor. I do smell like an aroma for all smells but it is the same odor just different strengths. It's almost like an acidic aroma.
