A little over two weeks ago, I was diagnosed with seasonal flu. The symptoms were an incredibly terrible headache and a constant 101 degree fever. The doctor prescribed Lortab for the headache. It did nothing but I took it for about 6 days. I also began taking Ibuprofin (sp?) to help alleviate the fever. After 8 days my headache and fever subsided. However, I was left with a muffled sensation in both ears and my tinnitus, which I have had for many years, was much more pronounced. Question: Why the symptoms and are they reversible?
