I get some kind of spasm occasionally, haven't had it for a while so I don't remember if it's in my tongue or throat. As I am old, I have been getting muscle spasms in muscles that I didn't even know I had. The last episode was upon waking from an evening nap and I had spasms in my shins so bad I was about ready to go to the hospital. I hate going to the hospital at night, so instead I grabbed my bottle of Kahlua, opened it and took a shot. Well, it worked so quickly.... those spasms melted right away. Don't know if that's appropriate for you to try or not...
but I would also see a doctor....
