Toenail fungus (also known as onychomycosis) is a common, but stubborn and difficult to treat problem. It sounds like you have already taken the logical first steps towards getting rid of it, but have not quite been successful. The best type of physician for you to see about this problem is a dermatologist
. A dermatologist will know what the best available treatments are for people that fail, or cannot tolerate Lamisil treatment.
Treatments for onychomycosis can be divided into the oral and topical medications. The melaleuca oil has not been tested in clinical trials, and probably will not get rid of your fungus. While currently lamisil is the best treatment there are other options. For example oral itraconazole in combination with or without a topical antifungal nail paint may work. Newer and more effective oral and topical medications are in the pipeline. Because of the multiple current and future options, I am confident that you will get this nail fungus taken care of.
I suggest that you schedule an appointment with a dermatologist. He or she can examine your toe nail fungus closely and determine which sub-type you have. From there, the doctor
can review which treatments you have already received and determine what the next best treatment is for you. Since you did not tolerate the Lamisil, then you might be placed on a different oral medication perhaps in combination with a topical one.
