When deciding whether to conduct an at-home pedicure or to take my sad feet to a podiatrist, I always use the skincare model. Maintenance and general care = an at-home job. Anything weird, red, painful = professionals need to enter the fray.
That said, in the case of both skin and feet, the chances of needing that professional to sort things out are always reduced if you do the home care — and yes I am well aware of how dull and ‘eat your greens’ that advice is, but we all know it’s true, so it’s worth putting in the graft.
