I have noticed that it's been painful wiping when I use the bathroom the last day or so but never thought anything of it. However, tonight I noticed that there is a small knot on the upper part of my inner labia. It's not painful unless I touch it. When I look in the mirror I can tell the difference in size. It really has me freaked out. It's almost like the under the skin acne. I've been having an increasing number of those on my face. My diet has changed in the sense I don't eat red meat anymore. I have no idea what this could be and google gave me 100 different answers.
