I'm all ears. I'm also getting toasty warm next to the stove. Tried the $$$ pills and the wife's tea tree oil treatment. Still have the fungus amongus.
Tea tree oil might reduce athlete's foot but seems to be ineffective for toe nail fungus. I tried it with no progress.
I would avoid pills. Potential side effects. I did Lamisil tablets twice; it beat back the fungus but did not kill it all. Lamisil can produce nasty side effects.
1. Carefully, patiently, cut, sand paper and file the infected nail way back to a very thin bed. I used an electric sander to begin with. You may prefer a slower approach. This step is absolutely key.
2. Apply Lamisil cream daily to the nail and surrounding toes. Lamisil applied topically does not appear to have the same side effects as orally ingested Lamisil (terbinafine).
If you have fungus on your foot, apply a thin film of Lamisil all over the foot.
I would also daily soak the affected toe along with the rest of the foot in vinegar. Fungus does not usually tolerate an acidic environment.
Spray the insides of your shoes, boots and wader socks with Lysol Disinfectant.
In general, keep your feet clean and dry. Think about wearing light wool socks in a sandal shoe configuration. Lose the cotton socks.
If you have diabetes or liver issues, you probably should consult a podiatrist or other qualified physician before proceeding even with just a topical application of Lamisil cream.
A few years ago, I went to see a podiatrist for plantar faciitis for an injury that resulted from scrambling down steep rip-rap rock of the kind you might find along a steelhead river near a logging road....
Nice chap from Colorado. He prescribed Lamisil cream for the observed athlete's foot and I believe that is what ultimately finished the toe nail fungus off.
Being a little crazy and desperate I might have on occasion layed down a base of DMSO gel on the infected toe nail bed before applying the Lamisil cream. DMSO is a good transport agent. It also has anti-inflammatory properties appreciated by horses and rock climbers alike. :-) You probably should not use DMSO gel unless you are literally healthy as a horse and willing to experiment.
