The pattern of it

Right.

Headache for three days running. It turned out I had barely drunk anything since Tuesday. Water, then a slow improvement, then feeling faintly stupid.

Manageable.

Sore at the injection site for about ten days, a small firm lump under the skin. The pharmacist looked at it, was unbothered, and told me to move further round next time.

Cramp in both calves in the night, twice this week. Mentioned it and had bloods done rather than being told to eat a banana, which I appreciated.

A rough few days. Not dangerous, just relentlessly unpleasant, the kind of unwell where you cannot read and cannot sleep and cannot settle to anything.

Someone is shouting.
