Waking up choking recently

Hello everyone, diagnosed 4 years ago RRMS, been on Tysabri subcut for about a year and a half now.

The past month or so I've had episodes where I've been waking up choking and unable to get a breath, it has sort of happened sporadically over the past couple of years but seems to be happening more frequently 😔

Is this even a MS related symptom? I've looked on Google and it mainly says about dysphagia, but I'm not sure me waking up choking is that.
