Do not worry.
The lumps for which you concern are the only enlarged lymphnodes
They will subside in few weeks to month.
Labrynthitis is aninfection of labrynth in inner ear
It may be viral or bacterial.
In your case , most probably bacterial.
Heavy antibiotics with antiinflammatory drugs will suffice to improve.
Blood tests may be done to rule out DM,HIV
or other diseases.
Repeat the course ,if there is relapse.
Immunobusters, healthy food,proper sleep,avoidance of worries will improve immunity and so the prevention of infection.
You consult ENT surgeon...
I hope you got my answer.
