I take Rebif for MS and expect to be switching to Ocrevus soon as they feel at 54 that I am transitioning from RRMS to SPMS. I don't have the symptoms you are experiencing but recently was prescribed Gabapentin to help with "nerve pain". My MS Dr reminded me it is "not a MS drug" ;-) but I see it referred to in many posts. It seems to be helping me. I see it listed as a drug to help spasticity and spasms for MS. I do have these symptoms and I would think it may help you? I was started on 2 pills (300 ea) and after my visit to Mayo last week am working up to 4. Effects last 6 hours so I will space them for maximum effect while I'd like to be active during the day but they also can help with sleep...so I will likely space them 6 hrs apart through the day. But for story time if you can't read the story, ie talk, maybe you could try another method? Like playing charades, can you sing instead? or play music? or do with puppets? Draw? There are so many ways to communicate other than speech...maybe you could switch it up and also the mental pressure of not having to speak may free it up. Just some ideas-
