This is just typical of my life.
Having gone through a course of antibiotics a few weeks back to get rid of a tooth abscess, I was persuaded by my dentist to have root canal work on the offending premolar to stop the abscess returning. This morning, after a fitful sleep, I woke up to find my jaw had swollen up (not quite like a melon but certainly resembling an average size satsuma). So, off I went to the dentist to discover that the surgery to stop me getting another abscess had given me, yes, you guessed it, an abscess.
This has been why I have been in such agony since Monday. Unfortunately, because my dentist had warned me that I might get some toothache for two or three days, it hadn't crossed my mind that it could be anything other than post surgery pain.
Anyway, it's back on the horse tablets for another week. I hope they take effect soon as, at the moment, I look like a lopsided hamster.
