Hi Chris - No, I've not had dental surgery on my jaw, and I don't have knee problems. I'm not sure if you're asking about the pain aspect? The pain your wife is experiencing could be from any one thing or a multiple of things. My pain is from multiple things. I hope she has good medical care. I do know though that when my pain level is high so is my fatigue level. It's hard to function when you don't have much energy to do so. I have to pace myself. It sounds like your wife is dealing with a lot of pain and fatigue. I couldn't say what is wrong either as I'm not a doc, but I hope your wife gets to feeling much better and gets the medical help she needs. I wish you both the best.
