Thanks for the response Dr Jeff it much appreciated, I’m going to speak to my GP about ordering the tests. Could please answer one other question and that is have you ever heard of my condition (Burning, chapped, sticky lips) being caused by Candida, there are no signs of fungal infection in my mouth (that’s been confirmed by an Oral Surgeon) I also don’t have any other symptoms, to be honest apart from the lip problem I feel quite good.
