Hello

Thanks for posting your query.

I can understand your concern.

It seems to be eczema on the auricle from the picture.

You will need to apply a steroid antibiotic combination cream on it like mometasone and fusidic acid cream.

These medications have excellent results and you will see good response in a week. You might need a prescription for the same.

However, I would recommend that you visit an ENT surgeon if possible, who can examine for the fluid leaking as that needs to be examined and treated accordingly.

Itching may be as a result of the ear eczema and also due to the infection inside the ear, if any present.

You can take an anti histaminic tablet like levocetrizine to control the itching.

Hope I have been able to answer your queries.
Please feel free to ask followup queries

Take care.
