The only visual poblems I can reliably note is the presence of floaters and flashers. The floaters are dots and a line. The flashers appear as pinpoints of light. The latter just happened recently. As for auditory changes, for the first time in my life I had vertigo. My doc believes it is/was labrynthitis caused by a viral infection. It's hard for me to understand why the sudden onset of this inner ear anomaly. But, judging by the number of people coughing and sneezing near me on the train, it probably is a virus!
