Hiccups
How many others get hiccups for what seems like a ridiculously long time and nothing helps(drinking water, holding breath etc) for what seems like weeks on end? I tend to blame everything on my ms whatever it is but I can't be crazy if it happens to more people lol
This has not been a problem for me, but it does seem like it could be neurological. Talk to your neurologist team, see if they have a fix?
