I read your query about muffled hearing after sinus infection
, though you are taking gabapentin
for nerve pain
for last two years.
I would like to tell you that that Gabapentin is not concern with your muffled hearing. Your hearing problem is due to sinusitis which is giving infection to your throat from time to time. Thus recurrent sore throat
interferes the working of Eustachian tube by blocking it thus ear clogging occurs.
I think it will be better to consult an ENT doctor for sinus operation or you may try for grommete insertion on your ear drum.
