Corn cap or salicylic acid ointment treatment requires long duration (2-3months) for effective result. You have to be careful to avoid friction & have to use soft footwear.
If you are having unbearable pain, then you will need excision (cut) of the corn. After Surgery, you can get back to normal work in 1-2days with caution for footwear, but the wound healing will take time 20-30days.
Next Steps
Consult a dermatologist for non-surgical management & a General Surgeon for Surgery.
