From history it seems that you might be having Corn
on palmer side of finger.
This type of corn is common in the sloe of foot but not uncommon at this site.
Apply corn cap very tightly on the part.
Keep it for 5days and open, there will be softening of the tissues surrounding corn.
Apply second corn cap again and keep it for 4-5 days more.
Corn will come out with corn cap.
Ok and take care.
