Has anyone had success with muscle relaxers?

I have had TTS many years and It keeps getting worse. Since a few days my left ear keeps spasming not only in response to everyday sounds, but even when I swallow, yawn, burp.... or just randomly. I am honeslt very close to the end. In the last year I have already tried carbamazepine, pregabalin and rivotril without any benefit. Does It make sense to beg a doctor for muscle relaxers? I think that If carbamazepine did not work muscle relaxers will supposedly be useless but I would like to hear If someone had a good experience.

I just please kindly ask not to suggest magnesium, relaxing, or things like that.
