I have been experiencing some dizziness with turning my head now for close to 3 weeks. I did have the whole nasal congestion when the weather started changing a couple weeks ago. I was taking OTC meds for that and had gotten better. Just in the last 2 days I have started with runny nose, hard to breathe, and now a dry cough. Is my dizziness related to all of my allergy/sinus problems or could it be something different? Also, based on my symptoms, do you think I could have an ear infection that I should take something more than OTC meds? Thanks!
