seeing alot of wart complaints in office. these are a viral infection. this happens as a result of some sort of break or insult to the skin allowing virus to seed. Once penetrated the virus creates its own blood supply. this leads to the spots one sees on the foot. the little black dots are actually capillary loops. You can prevent this by wearing flip flops at public pools and in public showers. Protect the feet! OTC wart medications such as liquid salicylic acid are a good treatment. even patches work well. Patients have not had alot of success with the dr scholl freezing treatments. when using topical treatments it is best to periodically go over the wart with a pumic stone or some similar device to remove dead skin. this allows for better penetration of medication.
