The way each doctor handles his patients and his post-operative procedures is up to the individual doctor. And it depends on what type of toenail surgery you had. If you had a 'sharp' toenail procedure and the physician used stitches, it will have to remain coverd and stay dry. If you had a more traditional toenail procedure without stitches, in my practice, the patient is soaking his foot and changing the bandages twice a day and then follows up in 2 weeks. I can not tell you to change the instructions your physician gave to you without knowing what was done specifically.
