What does an itchy, hard bump on the top of the foot with a fluid discharge indicate?

Hi,

Welcome to icliniq.com.

I understand your concern.

This looks like nummular eczema, and another possibility is irritant contact dermatitis to new footwear.

1. Is this happening for the first time?

2. Any history of eczema in the past?

3. Is it only on the left foot?

4. Is the right foot completely free of any rash?

Please stop using garlic, which can cause further irritation.

Clean the area with warm salt water using gauze.

I suggest applying topical mid-potent steroids like Triamcinolone acetonide 0.1 % cream twice after cleaning the area for two weeks. Consult a specialist, talk with them and take the medications with their consent.

Hope this helps.

Kind regards.
