I have progressive neurological diseases. As they progress, the same problems are happening to me. It’s gotten worse & it’s very painful. I’m 71. This didn’t happen when I was younger. I have fractures in L1, L2, & L3, stenosis from L1 to S1, but I don’t think these issues are the cause. I think it’s the neurological diseases. As they progress, this unintentional biting is much worse & more intense.
