Small dents in fingernails, vertical dents on thumb, scab on collar bone. Cause of concern?

Good afternoon, I have just found small dents in my fingernails, the majority of them are scattered or vertical but on my left- hand thumb the dents are vertical and just wondered if this means anything? I also have a black scab on my collar bone, it looks like a splinter but also has a bit of a red ring around it. Are any of these things anything to worry about? Thank you

Thanks for the query.

Dents on nails and rash on skin might be suggestive of psoriasis.

It is an autoimmune disorder.

A photograph would have helped me in giving a closer diagnosis.

Treatment can be with oral and topical steroids.

A biopsy may be required to confirm the diagnosis.

Please meet a dermatologist for final diagnosis.

Let me know if you have any other doubt.

Wishing you a good health.
Thank you
