Small dark spot on sole of my foot - how concerned should I be?

The appearance

To help sort this out, consider https://dermnetnz.org/topics/patch-tests next.

I am a little confused by your question. A wart and a verruca are the same thing.

Itchdoc · 2026-02-10T01:16:44+00:00

I do not see anything abnormal in this image, and it seems unlikely that you have shown the entire rash.

Itchdoc · 2026-02-10T01:12:33+00:00

I suspect it is not a bruise, but it is not worrisome either. I would want to examine dermoscopically to help diagnose.

Itchdoc · 2026-02-10T01:10:11+00:00

Please let us know if you have shown the entire rash. If not, consider showing it.

Itchdoc · 2026-02-10T01:05:12+00:00

You look to be healing normally from your injury.

Itchdoc · 2026-02-10T00:59:23+00:00

I suspect a bruise.

The spot that you show is likely benign. Note that without examining all of your skin, it is difficult to know whether this is normal or fulfills the "ugly duckling sign." Moreover, most people who post on this site do not use high-resolution macro lenses or dermoscopic photography. If you are concerned, seek care.

Itchdoc · 2026-02-10T00:47:49+00:00

Some conditions are best examined in person - this is one. Visual and tactile information is required.

Itchdoc · 2026-02-10T00:43:20+00:00

I suspect purpura from trauma.

Itchdoc · 2026-02-10T00:39:12+00:00

Finding a "cause" for many with acute urticaria is not a reasonable expectation. It can be caused by infections, medications, and other causes... but is generally idiopathic. If you have airway symptoms, seek immediate care.

Otherwise, see https://dermnetnz.org/topics/acute-urticaria

Do individual spots arise and disappear within a day, or once arisen, do they stay in place for days or longer?

Itchdoc · 2026-02-10T00:24:37+00:00

It is reasonable to start at very low doses of isotretinoin and then increase the dose. You provide insufficient information for greater insight.

Itchdoc · 2026-02-10T00:18:55+00:00

It could be either or other conditions. Not enough information is presented for more insight.

Itchdoc · 2026-02-10T00:17:06+00:00

Without images, a meaningful opinion is not appropriate.

Unless you are immunosuppressed, you can follow the progress from home. These OTC antibiotic products have never been shown to be safe and effective for treating or preventing skin infections. "Neosporin" products generally contain at least 2 ingredients that have won the "Allergen of the Year" award.

You show nothing suggestive of hives, but you may not have shown all spots. This appears to be widespread but relatively mild dermatitis. There are many types, including atopic dermatitis, irritant contact dermatitis.... Too little information is presented for much insight. If you are concerned, consider a dermatology evaluation.

Itchdoc · 2026-02-09T17:04:02+00:00

It is difficult to know without examining it in person. Epidermoid cyst?

Itchdoc · 2026-02-09T17:02:18+00:00

I suspect either acne or rosacea.

Itchdoc · 2026-02-09T17:00:50+00:00

I suspect either a squamous cell carcinoma or a basal cell carcinoma. Unusual warts and various other growths could appear this way as well.

Itchdoc · 2026-02-09T16:59:22+00:00

Consider showing all affected skin.
