Well, vertigo is a common symptom of MS. I don't think it'll hurt to see an ENT to maybe see if fluid in the ears is the cause. If it is, than great! Maybe you can get some relief. If not, I don't see how seeing a specialist would hurt. If it's just the crappy vertigo that's caused by MS, maybe the specialist can offer some tips on coping with it or making the symptoms feel less severe.
I had severe vertigo once, it was horrible. I wish you the best and Happy New Year to you too.
