"You may experience a slight soreness in your arm"
For "slight soreness", read, "hot, hard, throbbing, painful lump, two inches in diameter, which takes days to go down"*.
For "mild fever and slight muscle aches", read, "shivering uncontrollably for 48 hours to the point where your teeth rattle together; curled up in bed round a hot water bottle; painfully aware of every joint in your body".
"It can't cause flu". I know this. You tell me this every year. I know that what the flu jab causes isn't actually flu. But - after seven years of the bloody things - I also know that what it causes isn't slight soreness and a mild fever, either.
I am not a hypochondriac and I am not - over this, at any rate - a drama queen. I know why I need to have a flu jab, and I accept that it makes sense to have one, despite what it always does to me. All I ask is that you don't insult my intelligence by pretending that the side-effects I experience are mild.
