An unexpected side effect of my gastroscopy was an unpleasant chest infection. This manifested itself when I started coughing blood as I lifted down my case on the 146 after positioning to ABZ on my first day back at work after the gastroscopy. This was particularly worrying as my only previous experience of this was when I had a pulmonary embolism following DVT so I was fearing the worst - heparin drips, long-term warfarin, frequent visits to the phlebotomist and probably the end of my flying career.
Fortunately, 'just' an infection was diagnosed and a course of Amoxil cleared it up. Phew!
