Brief Answer:
Take 
Betahistine and 
Prochlorperazine tablets
Detailed Answer:
Hi there,
Thanks for your query.
I need more information :-
*   since when do you have this problem?
*   Is there associated 
nausea or 
vomiting along with spinning sensation?
*   Does spinning sensation occur on turning your side while lying down?
*   Do you hear ringing in the ears?
*   Are you able to walk without swaying or the room spinning?
Nevertheless, the brief information provided points towards either, 
     1.     a common condition of internal ear problem (called 
Labyrinthitis); or,
     2.     A benign, transient condition called Benign Paroxysmal Positional 
Vertigo (BPPV).
The treatment is the SAME for both conditions.
I recommend that you take:-
#    Tablet Betahistine 16mg thrice daily x 3 days; thereafter, 8mg THRICE daily till you recover completely.
#    Tablet Prochlorperazine (an anti-histaminic, anti-emetic drug) twice daily, along with Betahistine, till you have complete recovery.
You will be completely OK within 7-10 days.
Consult your doctor and apprise him of my opinion. I am certain that he will agree  with my opinion;  order required tests, and will prescribe the advised drugs in appropriate doses.
Hope I have addressed to your concerns to your complete satisfaction and you find my response helpful and informative. I will be happy to answer further queries, if any.
Fond regards and have a nice day,
Dr. Rakesh Karanwal
