I just saw this. I had this problem in the last year. For me, the pain was unbearable and bizarre. I went to my PCP and he put me on a med specifically for this problem. I also immediately started wearing a mouth guard to bed. Within a month, the symptoms just about went away. I was so happy, because it could become a permanent affliction. You might try what I did.
Thanks. I'm not really in pain but something bizarre is going on for sure.
