MrsD's thoughts are good, you have had the snuffles recently and head colds like that can cause tenderness.

However....yeah even pillows hurt. I get an awful lot of pain at my impact site (from where a car door was slammed with a persons fullforce into my head: from jaw, across cheekbone, locking mechanism just above temple and extending over my ear and into the top of my skull.)

In the early days it was agony to lay on that side, but worse on the other as I felt my brain was too heavey and pressure would build. Now I have to remember to move very carefully, though it is improving.

Is your pain general or localised and what sensations?
