About Dr Andy Teh

I experienced several common side effects of the Pfizer-BioNTech COVID-19 vaccine in November 2021, such as injection site inflammation, myalgia, and nausea. However, the most annoying complications of the vaccine were brain fog and vivid and intense dreams, which lasted ten days.

Over the past nine months, three laboratory-based fasting blood glucose tests yielded measurements at or above the American Diabetes Association’s cut-point for prediabetes. However, some factors point against a diagnosis of prediabetes, and there is at least one alternative explanation for my abnormally high fasting blood glucose levels.

Left-sided sciatica I developed in December 2021 appears to be improving after weeks of avoiding running, rowing, and cycling. Sleeping face up with a thin pillow under my calves has also helped.

My bilateral carpal tunnel syndrome recurred in mid-November 2021 and worsened in the ensuing weeks. The symptoms in my hands and fingers eventually came under control in mid-January 2022 with conservative treatment and the addition of an Apple Magic Trackpad 2 to my desktop setup.
