I have had facial pressure and dizziness since May 2. I did have a sinus infection but CAT Scan has said my sinuses are clear. ENT gave me a balance test and a brain MRI. All clear. I am a diabetic and have been running very high blood sugars when I have been on the many antibiotics and Prednisone. I am now experiencing some neuropathy in my hands and feet - do not know if it is related to my mysterious condition or a result of the long periods of high blood sugar. Would appreciate any input. Thanks !!!!
