About 4 weeks ago, I woke up to a spinning room, it settled down. When to doctors and she told me could be viral infection of inner ear. Took antihistamine and nose spray. Since my one ear was clogged and sinuses felt the same. Seemed to help, but periodically, usually in morning I feel very light-headed. Thought perhaps BPPV and did the epley manuever. Would feel great for a few days then, it happens again.
