All seems to be healing up quite nicely. I put on a dry dressing overnight so as not to catch the stitches on my pillow, and in the morning there are little spots of blood that correspond to the eight entry and exit sites of the four stitches. I've had less discomfort each day, easily banished with paracetamol.
I've made an appointment to get the stitches out on Tuesday, and I'm quite excited about getting rid of them. I think most of the discomfort comes from them, now. I do remember how excited I was about having the operation - and that had I known that it would feel like the surgeon was digging out the cyst with a sharpened dessert spoon my enthusiasm would have been lessened. What do you mean, of course he wasn't - I know what I felt.
Anyway I'm sure that taking out the stitches will be unpleasant, too, but afterwards I'll be able to move my head without that sharp reminder.
