Re: Thick skin on big toe
There are a number of reasons why skin might thicken or present with an over-growth or keratotic overlay. Without knowing the specific reason in your case, it could possibly be unsafe or inappropriate to recommend a treatment which you would then provide yourself without supervision. A podiatrist or dermatologist would normally charge for only an initial office visit and possibly but not probably a biopsy for a diagnosis. As cost is your concern, you could likely get a realistic estimate by calling the doctor of your choice. It can then be determine whether it is something that requires treatment and who would best provide it.
