"Beware!! Make sure your podiatrist tests your nails for fungus! I saw 3 podiatrists that did not test and wanted me to take Lamasil. I refused to possibly trade my liver for pretty nails. So, when podiatrist #2 suggested removing the nail and using topical Jublia when it started growing back in, I jumped on it, thinking topical is safer. Within 2 weeks of using Jublia ALL my toes became affected and red and blistered. I thought I had athletes foot, so I continued while using foot powders and sprays too! 2 dermatologists later I never had fungus; it was psoriasis!! 

Jublia was a "traumatic " event to my toe nails and made the underlying psoriasis go nuts. Now over a year and a half later, I have psoriatic arthritis in my feet and hands."
