Berber19, it seems covid often causes weird neurological issues afterward, and autonomic dysfunction could cause some of your symptoms. If no occult infection is found to explain the high WBC and neutrophils, I would suggest you take a look at the possibility of Cushings disease, excess cortisol production from the adrenal glands. It is rather rare but could explain the high white counts, high glucose and even low potassium, and hair loss. It’s like being on Prednisone, but from an internal source-overactive adrenal glands. This can be tested by an 8:00 am serum cortisol level, a simple blood test. Also, it’s normal for glucose to be high for 2 hrs after eating, so glucose measurements should be done fasting or after 2 hrs from eating. I hope your dr will check a cortisol level.
