Oooh last night was a bad one. I have a cold and maybe that interacted with it, but I was practically writhing with pain in my left jaw joint many times. I kept going back to sleep and then surfacing again and again. It felt like someone had bashed my jaw joint with a hammer. Naturally I felt awful today.
Tonight I will take anti-inflammatories. Maybe I will take them solidly for a couple of days.
A new 'bump' had appeared below my jaw joint yesterday. It feels a bit jelly-like. There is a much smaller version below my right jaw joint. I think it's a muscle. I suspect I've been forcing my mouth open too hard during my jaw exercises.
