Well, I created the account only for this, so I feel pretty bad right now :( .. I'm sorry. I thought maybe this might help some of you..
Haha, I'm not skinny, I'm "normal" I guess :). I know everyone manifests it differently, so don't even worry about that! If your results show positive, that is good enough! I have a friend that gets a skin rash if he glutens, so everyone is different!
Also, I don't have any pictures! I never thought of that. To describe it, it was basically a peeling cycle (usually around 3 days), and my lips would go white when in contact with water. The pain only happened after they peeled, due to how sensitive the new raw skin was. The swelling was not huge, but was definitely there.
I was diagnosed by a clinical doctor, not a dermatologist.
Also, if your entire house is not gluten-free and you are eating out often, it is very likely that you are still glutening, which is why you are not healing as fast! (I'm not a doctor, but I am a Celiac :) and I'm VERY strict when it comes to cross-contamination). It only takes a small, imperceptible amount. If you have doubts, you can have someone take a look at your intestines, though I've heard its not a nice study to get done! But that will for sure tell you if you are glutening or not, depending on how hurt your intestines are :) !
