I have toenail fungus that is spreading to my other toes that keeps getting worse.how do i get rid of it?

Anti-fungal meds: This is going to be a long term treatment over 6 months because your nails grow very slow. It can be done with one pill a week but you have to get this sorted thru your doctor.

Undecylenic Acid: This is an antifungal solution which you can dab over the infested toenails. Do this twice per day. It is highly effective. Most larger drug stores will have this. There is also a cream version called Desenex which has the same product in it.
