The fungus is in your blood stream. I had my nails so bad I never knew why so many of them were even still hanging on. My doctor prescribed a heavy duty antibiotic I think it was terrafine but I am sure it is close. It was a ninety day course and I had to get a blood panel test to check my liver once a month on it. After the meds I had been warned I would not see any improvement for months. The doctor did well and everything went as he predicted. It even got rid of some athletes foot I had as well.
