What Causes Continuous Cough, Chocked Nose And Hearing Loss In One Ear?

I AM HAVING PROBLEM OF CONTINUOUS COUGH. MY NOSE IS ALWAYS CHOCKED. I KEEP ON BLOWING BUT IN THE YR 2000 I STOPED HEARING FROM MY RIGHT EAR. IN 2005 FIRST I HAD FEELING AFTER LUNCH THAT ALL THE THINGS AROUND ME STARTS MOVING. I WAS SWETING AND UNABLE TO HOLD MY SELF. AFTER SOME TIME I VOMITED AND THIS STARTED AND LONG LASTED TILL FURTHER 2YRS. DURING THIS PERIOD ALL THE POSSIBLE TESTS WAS DONE SUCH AS 2/2D ECO,STRESS TEST,ALL TYPES OF BLOOD CHECKING,MRI CT SCAN. THE RESULTS WERE NEGATIVE. IT COMES SUDDENLY AND GOAN SUDDENLY. NOW FROM DAY BEFORE IT AGAIN STARTED BUT THE SPAN OF BEING BED RIDDEN HAS COME DOWN TO 15 MNTS AS AGAINST 8 HRS. DURING THIS PERIOD I GOT MY EAR CHECKED. RIGHT EAR LOST THE AUDIBILITY TO THE EXTENT OF 70%. DURING THIS MY ACIDITY SUDDENLY GOES VERY HIGH. AS PER DR (INDIA) I AM TAKING VERTIGO 16,STEMETIL. IS IT OK. OR U ADVICE SOME THING ELSE.
