Hi Alf

It can be difficult to eradicate nail fungal infections. Often treatments are long and folk get tired of waiting for results. Results show as the nail grows out and this of course takes several months to happen. I would suggest Gehwol nail solution (Clotrimazole) to paint the nails to help prevent fungal nail infections in your case as a preventative. See
