Thanks for writing to H.C.M. for your query.
I have gone through your query regarding severe pain
in ear of your daughter, and she had been given treatment for fungal infection
in her external ear of same side about 45 days back. she had completely recovered from fungal infection.
Now shooting pain in ear indicates towards recurrence of fungal infection, but as you said that now her ear canal
and ear drum is normal therefore I rule out fungal infection. The other possibilities are-
(a) Acute otitis media
(b) Reffered Otalgia.- Means here ear remains O.K. and pain gets reffered to ear from- Molar teeth, posterior half of tongue, tonsils, throat.
To reach to final diagnosis you are advice for these investigations-
(a) C.T. scan ear (HRCT) to rule out pathology.
(b) Audiometery- Pure tone and Impedance audiometery.
A thorough examination and co-relation of inferences of investigations will help in reaching to correct diagnosis which may accordingly be managed.
