I wrote several weeks ago about some erosions on the head of my penis. I was told it could be balanitis and possible yeast. I have been using colloidal silver spray on it and it has almost disappeared. Now, i noticed on the inside of my mouth on the inside cheek, there is some "roughness". When i looked at it, it looks like white "streaks". I looked up thrush, and when I looked at the pictures of Lichen Planus, it looks like that. could it be Lichen Planus on the penis as well.....and what is the treatment for that? Thanks
