Brief Answer:
It could be some variant of dermatitis

Detailed Answer:
Hi,
Thanks for writing to us.
Going by the short description you have provided, it could be
seborrheic dermatitis- if this area is red and has greasy scales
allergic dermatitis- due to some allergen. could be red, bumpy and scaly.
insect bite induced itching and burning- area could be red dry with small blisters

Usually in allergic or seborrheic dermatitis, oral prednisone helps. As you did not have much response with the same, it is important to know the dose and duration of prednisolone taken.

I would appreciate if you would let me know
since how long are you having this
dose and duration of prednisolone and name of antibiotic prescribed
description of lesion- scaly, bumpy, pus filled, oozing
any history of contact with any allergen esp any new ear drop used or earrings worn.
if having scalp dandruff
if there is any history of insect bite

please upload an image of affected area too.


in the interim, please take tablet cetirizine twice daily and apply hydrocortisone cream.
Hoping to hear from you soon.
Take care

Detailed Answer:
Hi,
Thanks for writing back.
You took prednisolone in high dose for short while. Now ideally had it been seborrheic or allergic dermatitis, it should have responded to prednisolone.

If we think of it as an inflammatory swelling, then there could be a possibility of having an ear infection( otitis media) or impacted wax which could have led to swelling of external ear but in such case there should be some earache or ear discharge. The same can be ruled out in your case by ear examination.
Cellulitis too can be a remote possibility
Now these two conditions should respond to antibiotic. As you have started it since yesterday only, so response might need some time. Also for better response I would suggest that you take oral antihistamine like cetirizine and an oral inflammation reducing pain killer like Brufen.

Hope this helped.
Take care
