2 years back I had a severe sinus infection. Eyes blurry, off balance, every time I moved I felt like I might fall. Fog head city. No appetite, weak, the whole enchilada.
I was surprised it was my sinuses because I didn't have a runny nose, or any sneezing....but I had the weird eye thing going on and balance issues.
Antibiotics had me back to normal in a day.
Recently, same symptoms again......totally forgot about the previous sinus infection. This time it was sinus/ear infection. Again, no sinus/ear infection symptoms....but no appetite, very week, dizzy, and all the above symptoms from 2 years ago.
Again, antibiotics got rid of the feelings within 12 hours. ( I was on antibiotic for 10 days).
Something you may want to have checked out if you haven't already.
