Has your Doctor taken blood work from you if you are on the Lamisil? They have to keep track of your liver when you are on this medication because Lamisil can cause so much damage to liver, eyes I read that someone's tongue remained numb even after months of going off of the meds. Lamisil is dangerous and should not be taken into consideration lightly. I refused to take it when my Dr. said I would have to have weekly blood tests to make sure my liver was still working week to week on that stuff. I came to the conclusion that my liver was more important then my toenail.
I have had the fungus in my bie toenail for five years and Marti recommended Thymol drops and it is working for me. It takes patience because your entire infected nail has to grow off ( takes between 6 months to 1 year), but the Lamisil will take just as long as the nail has to grow off in any treatment you try or use. Good Luck to you but my advice is to stay away from the lamisil.
