Respiratory Infection

On sep. 17 I noticed my head was somewhat foggy so call it. I really did not feel like myself. I made an appoinment with my local doctor and he stated that I had an upper respiratory infection he gave me Amox/clav 875mg/125mg (antibiodic) as well as veramyst and Xyzal (5mg) he told me to take Amox/Clav for 10 days and then take the Xyzal for 7 and to use the nose spray for 7 days as well. I have been taking these pills for about four days now and really have not noticed much difference in my brain fog. I am just wondering if anyone had a similiar problem and how I can get rid of this. Please Help. Tom

If your doctor is right that your symptoms are related to an upper respiratory infection, it may be that not enough time has passed for the infection to resolve.  On the other hand,  if your feeling "foggy" is a completely new experience for you and does not resolve very soon, you and your doctor might want to reconsider the diagnosis and begin to look for other causes including metabolic, migraine variant or another central nervous system disease.
