Suggest Treatment For Warts
Wart/Verruca vulgaris
Detailed Answer:
Hello and welcome to healthcaremagic
I am Dr. Kakkar. I have gone through your query and I have understood it.
I have also seen the picture.
This looks more like a wart. I can see thrombosed capillaries as red dots. Moreover this is an unusual site for a callus.
Treatment of warts and corns is generally the same. You have to use a topical keratolytic preparation (salicylic acid 17%w/v+lactic acid 17%w/v liquid) once daily at night over this area. First of all soak the finger in lukewarm water for 15 min and the apply keratolytic preparation.
Slight scrubbing with a pumice stone would help remove dead skin and allow the keratolytic preparation to penetrate better.
You may also gently pair the dead skin with a blade every 2-3 days as it gets softer.
