Hi. I have a general feeling of fuzziness in my brain, accompanied by some light swooshing noises in my head when I move it. I had flu like symptoms since last week, developed severe dizziness yesterday, so visited my GP. Based on a slight amount of fluid behind my right ear and my history of allergies, He prescribed Claritin, Pepcid AC, nasal spray, and gave me a sot of cortisone. The dizziness isn t as bad as it was, but now this other symptom arose. I have also had an extremely bad cough for a week now, so he prescribed robitussin with codeine. I only take it at night so I can sleep. My big worry is the brain fuzziness. Any suggestions?
