I have had these symptoms for 2 year...they come and go...not every day ...but sometimes sets in for days at a time then stop and then start again. The tip of my tongue goes numb, nose stops up, ears ring, but worst of all my eyes will not focus...only at book length. Now it is beginning to affect my legs and arms and a few days ago my right side never got back to normal for days...if it really has. Been to many many doctors they can not find out what it is...the only 2 medicines that I am still on that I was when it first started is Ranexa and Prilosec .
