Firstly, It can be due to vit B deficiency. Take some vitamin B complex for some days and see if your symptoms improve.
Secondly, it can be due to atopic dermatitis or eczema ("Atopic" refers to a group of diseases where there is often an inherited tendency to develop other allergic conditions, such as asthma and hay fever). Cheilitis(Inflammation of the skin on and around the lips)is often seen in atopic dermatitis. Diagnosed by blood test like RAST. Treatment is by topical steroids or oral therapy of corticosteroids in severe cases. Topical creams like tacrolimus ointment (Protopic) and pimecrolimus cream (Elidel) are also useful. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Did you ever get a resolution to your dry lip patch issue. I'm having something similar and am curious.
Hi all i just posted this on another thread for the same problem as I know how irratating it is and want to help others experiencing the same thing. I had the same problem for several weeks dry patch on my upper lip and when i rubed my lips together it felt awful no pain just extreamly irritating and i noticed it constantly until my doctor recommended using blistex conditioning lip balm. It went away within two days please try this it was such a simple solution. The diagnosis for the rough patches on your lips is sevearly dry skin that won't be moisturized by most lip balms or vasaline please try blistex it is $4.00 is aus and worth every cent. Let me know how you go!
My problem is very dry patch right above my upper that won't seem to go away. I noticed it last year while I was busy. when I'm doing something at a fast pace like multitasking it gets this gooey and moist and I ,can peel it off. I have dry mouth due o some of the meds I take, but I always had but this just started happening,,When I settle down and I clean it up it still doesn't go away it dries up and it looks like have a big upper lip. It is red in color when it dries..So frustrated...
