From the symptoms you have described it seems like you have had a infection of the inner ear/ labyrinth usually they present with typical symptoms of hearing loss
. This usually occurs following a upper respiratory infection
The best medication is a course of oral steroids
given at high doses for about 20-30days with some vasodilator drugs like pentoxyphylline and multivitamins with antoxidants. Some ENT specialist
repeat the course if they dont see an improvement in hearing.
The prognosis of this is variable with some recovering completely ie no hearing loss, vertigo or tinnitus and there are some who dont improve despite medications and may remain one or more of the symptom. It is very hard to tell who fits
in which category. If your hearing has not improved even a little despite medications for > 8 weeks then Im sorry to say the chances are poor.
Vertigo gets better by time and with vestibular exercises- cawthorne cooksey exercises. Look into them on websites and start doing them regularly to reduce the Vertigo.
It is better to visit a Vertigo specialist/ ENT specialist to get the best plan of action.
